∠, the angle symbol in Unicode is List of XML and HTML character entity references | U + 2220

The proposed encoding does not use the lexical encoding model used in the existing ISO-IR / 169 registered character set, but instead applies the Unicode and ISO character-glyph model to the Bliss-character model already adopted by BCI, since this would significantly reduce the number of needed characters.

There are many other encodings, which represent each character by a byte ( usually referred as code pages ), integer code point ( Unicode ) or a byte sequence ( UTF-8 ).

Common examples of character encoding systems include Morse code, the Baudot code, the American Standard Code for Information Interchange ( ASCII ) and Unicode.

If the character encoding for a web page is chosen appropriately then HTML character references are usually only required for a markup delimiting characters mentioned above, and for a few special characters ( or not at all if a native Unicode encoding like UTF-8 is used ).

* Cygwin 1. 7 introduced comprehensive support for POSIX locales and many character encodings, whereby the UTF-8 Unicode encoding became the default.

A collation algorithm such as the Unicode collation algorithm defines an order through the process of comparing two given character strings and deciding which should come before the other.

The simplest kind of automated collation is based on the numerical codes of the symbols in a character set, such as ASCII coding ( or any of its supersets such as Unicode ), with the symbols being ordered in increasing numerical order of their codes, and this ordering being extended to strings in accordance with the basic principles of alphabetical ordering ( mathematically speaking, lexicographical ordering ).

Since April 2008, the character encoding standard Unicode includes characters that represent the double-six domino tiles in various orientations.

ICANN has approved the Internationalizing Domain Names in Applications ( IDNA ) system, which maps Unicode strings into the valid DNS character set using Punycode.

Unicode solves this problem by assigning every known character its own code ; if this code is known, most modern computer systems provide a method to input it.

* ICU Charset Mapping Tables Contains computer readable Unicode mapping tables for EBCDIC and many other character sets

The Fahrenheit symbol has its own Unicode character: "℉"( U + 2109 ).

If each character is stored in 8 bits ( as in ASCII or ISO Latin 1 ), the table has only 2 < sup > 8 </ sup > = 256 entries ; in the case of Unicode characters, the table would have 17 × 2 < sup > 16 </ sup > = 1114112 entries.

** Support for supplementary Unicode character sets utf16, utf32, and utf8mb4.

* Numeric character reference, a way of including a Unicode character in a web page

Unicode has a separate code point for the ohm sign ( U + 2126, Ω ), but it is only included for backwards compatibility and the Greek uppercase omega character ( U + 03A9, Ω ) is preferred.

* Strings: A sequence of characters surrounded by quotes is equivalent to a list of ( numeric ) character codes, generally in the local character encoding, or Unicode if the system supports Unicode.

* « Plain text is a pure sequence of character codes ; plain Unicode-encoded text is therefore a sequence of Unicode character codes .»

The proportionality operator "∝" ( in Unicode: U + 221D ) is sometimes mistaken for alpha.

Uppercase and lowercase Greek alpha are represented in Unicode as U + 0391 ( Α ) and U + 03B1 ( α ) respectively.

For example, use of ( which gives é, Latin lower-case E with acute accent, U + 00E9 in Unicode ) in an XML document will generate an error unless the entity has already been defined.

However the ConScript Unicode Registry has defined the to U + E0FF range of the Unicode " Private Use Area " for Cirth.

Using Unicode characters, the faces < big >&# x2680 ; &# x2681 ; &# x2682 ; &# x2683 ; &# x2684 ; &# x2685 ;</ big >, can be shown in text using the range U + 2680 – U + 2685 or using decimal.

It is encoded in Unicode as U + 025B (" Latin small letter open e ", ) and U + 0190 (" Latin capital letter open e ", ) and is used as an IPA phonetic symbol.

* The lowercase iota symbol has Unicode code point U + 03B9 and the the uppercase U + 0399.

The crossed swords symbol (⚔ at Unicode U + 2694 ) is used to represent battlegrounds on maps.

For example, a Unicode code point like U + 5408, which corresponds to a particular Chinese character, has to be converted to a decimal number, preceded by and followed by, like this:, which produces this: 合 ( if it doesn't look like a Chinese character, see Template: Special characters ).

A circle with a dot at its centre ( Unicode U + 2299 ⊙) indicates a vector pointing out of the front of the diagram, toward the viewer.

A circle with a cross inscribed in it ( Unicode U + 2297 ⊗) indicates a vector pointing into and behind the diagram.

The symbols are encoded in Unicode at positions U + 2648 to U + 2653 in the Miscellaneous Symbols block.

UTF-16 ( 16-bit Unicode Transformation Format ) is a character encoding for Unicode capable of encoding 1, 112, 064 < ref >, where is the BMP, is the interval U + D800 – U + DFFF, and are the higher planes .</ ref > numbers ( called code points ) in the Unicode code space from 0 to 0x10FFFF.

Today it has its own Unicode point, distinct from Greek lowercase mu, to acknowledge and encode its semantic power.

Uppercase and lowercase Greek chi are represented in Unicode as and respectively.

The Unicode character encoding standard originally ( since version 1. 1 of 1993 ) had only a single codepoint for Koppa ( U + 03DE " Greek letter koppa ") which was marked as uppercase and could be used either for an epigraphic or a numeral glyph, depending on font design.

The micro sign or micron is considered a distinct character from the Greek alphabet letter by Unicode for historical reasons ( although it is a homoglyph ) and is found at U + 00B5 as well as position B5 < sub > HEX </ sub > in ISO 8859-1, 3, 8, 9, 13 and 15, and thus in the corresponding Windows code pages Windows-1252 etc.

Almost all electronic mail messaging was also using Greeklish, and only recently, with the introduction of full Unicode compatibility in modern e-mail client software and gradual replacement of older programs, that usage of Greek characters became widespread.

Around 2004, after most computer software became compatible with Unicode UTF-8 or UTF-16 systems, use of Greeklish was strongly discourraged in many Greek online Web discussion boards ( forums ) where Greeklish was in use before.

In Unicode, the code points assigned to the smooth breathing are for Greek and for Cyrillic.

Everson has been actively involved in the encoding of many scripts in the Unicode and ISO / IEC 10646 standards, including Avestan, Balinese, Bamum, Bassa Vah, Batak, Braille, Brāhmī, Buginese, Buhid, Unified Canadian Aboriginal Syllabics, Carian, Cham, Cherokee, Coptic, Cuneiform, Cypriot, Deseret, Duployan, Egyptian hieroglyphs, Elbasan, Ethiopic, Georgian, Glagolitic, Gothic, Hanunóo, Imperial Aramaic, Inscriptional Pahlavi, Inscriptional Parthian, Javanese, Kayah Li, Khmer, Lepcha, Limbu, Linear A, Linear B, Lycian, Lydian, Mandaic, Manichaean, Meitei Mayek, Mongolian, Mro, Myanmar, Nabataean, New Tai Lue, N ' Ko, Ogham, Ol Chiki, Old Hungarian, Old Italic, Old North Arabian, Old Persian, Old South Arabian, Old Turkic, Osmanya, Palmyrene, Phaistos Disc, Phoenician, Rejang, Runic, Samaritan, Saurashtra, Shavian, Sinhala, Sundanese, Tagalog, Tagbanwa, Tai Le, Tai Tham, Thaana, Tibetan, Ugaritic, Vai, and Yi, as well as many characters belonging to the Latin, Greek, Cyrillic, and Arabic scripts.

Nevertheless, in the Unicode encoding standard, the following three phonetic symbols are considered the same characters as the corresponding Greek letters proper:

Mathematical Alphanumeric Symbols is a Unicode block of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles ( one example is blackboard bold, called " double-struck " in Unicode terminology ).

Cyrillic was based on Greek uncial script, and adopted Glagolitic letters for some sounds which were absent in Greek — it also had some letters which were only used almost exclusively for Greek words or for their numeric value: < span class =" Unicode "> Ѳ, Ѡ, Ѱ, Ѯ, Ѵ </ span >.

As well as additions to the Unicode blocks partially covered by earlier releases, the font included new glyphs for Latin, Greek, Shavian, and the following Unicode blocks:

At the same time, the TLG undertook the project of working with the Unicode Technical Committee to include all characters needed to encode and display Greek in the Unicode standard.

Unicode incorporates numerous writing systems, and, for a number of reasons, similar-looking characters such as Greek Ο, Latin O, and Cyrillic О were not assigned the same code.

Although many of its characters are also used in standard Latin, Greek, Cyrillic orthographies or the IPA, and are found in the corresponding Unicode blocks, many are not.

There is, however, room for disagreement on whether two Unicode characters really encode the same grapheme in cases such as the " micro sign " µ vs. the Greek μ.

This should be clearly distinguished from Unicode characters that are rendered as identical glyphs or near-identical glyphs ( homoglyphs ), either because they are historically cognate ( such as Greek Η vs. Latin H ) or because of coincidental similarity ( such as Greek Ρ vs. Latin P, or Greek Η vs. Cyrillic Н, or the astronomical symbol for " Sun " ☉ vs. " circled dot operator " ⊙ vs. the Gothic letter vs. the IPA symbol for a bilabial click ʘ ).
