The Cirth are not yet part of the Unicode Standard.

According to The Unicode Standard,

According to The Unicode Standard, plain text has two main properties in regard to rich text:

* « The Unicode Standard encodes plain text .»

* « The distinction between plain text and other forms of data in the same data stream is the function of a higher-level protocol and is not specified by the Unicode Standard itself .».

Developed in conjunction with the Universal Character Set standard and published in book form as The Unicode Standard, the latest version of Unicode consists of a repertoire of more than 110, 000 characters covering 100 scripts, a set of code charts for visual reference, an encoding methodology and set of standard character encodings, an enumeration of character properties such as upper and lower case, a set of reference data computer files, and a number of related items, such as character properties, rules for normalization, decomposition, collation, rendering, and bidirectional display order ( for the correct display of text containing both right-to-left scripts, such as Arabic and Hebrew, and left-to-right scripts ).

UTF-8 encodes each of the 1, 112, 064 code points in the Unicode character set using one to four 8-bit bytes ( termed " octets " in the Unicode Standard ).

Although their Adobe glyph names are commas, their names in the Unicode Standard are " g ", " k ", " l ", " n ", and " r " with a cedilla.

Rules for Han unification are given in the East Asian Scripts chapter of the various versions of the Unicode Standard ( Chapter 12 in Unicode 6. 0 ).

The organization was founded to develop, extend, and promote the use of the Unicode Standard.

Neither is UTF-7 a Unicode Standard.

* Unicode support ( however prior to 5. 5. 3 UTF-8 and UCS-2 encoded strings are limited to the BMP, in 5. 5. 3 and later use utf8mb4 for full unicode support )

In Unicode 5. 2, four swastika symbols were added to the Tibetan block: U + 0FD5 ࿕ ( right-facing ), U + 0FD6 ࿖ ( left-facing ), U + 0FD7 ࿗ ( right-facing with dots ) and U + 0FD8 ࿘ ( left-facing with dots ).

It was based on Ability Office 5, the first and only major release of Ability Office supporting Unicode at the time.

The characters and are encoded in Unicode since version 5. 2.

It has been included in Unicode since version 5. 1.

The 16-bit fixed width encodings, such as those from Unicode up to and including version 2. 0, are now deprecated due to the requirement to encode more characters than a 16-bit encoding can accommodate — Unicode 5. 0 has some 70, 000 Han characters — and the requirement by the Chinese government that software in China support the GB18030 character set.

Unicode 5. 1 also includes "⸘" ( U + 2E18 INVERTED INTERROBANG ), which combines both in one glyph.

Neither CenterICQ nor CenterIM 4 support Unicode, but support for UTF-8 is planned for CenterIM 5.

The Unicode Standard 5. 0 only lists UTF-8, UTF-16 and UTF-32.

4NT and Take Command / 32 were released in both ANSI ( Windows 9x ) and Unicode ( Windows NT ) forms, with the ANSI version dropped at version 5.

The fourth edition constitutes a major update and rewrite of the book for Perl version 5. 14, and improves the coverage of Unicode usage in Perl.

HAN NOM A and HAN NOM B are free fonts, which include all the characters in the Extension A and the Extension B, more exhaustive than SimSun-18030, or even than Simsun ( Founder Extended ), but they don't support all code points defined in Unicode 5. 0. 0 either.

* The Unicode Standard, Version 5. 2: Conformance ( see Section 3. 7 for Decomposition ).

It was encoded in Unicode 5. 1 at positions U + A652, and U + A653.

As of 2009 Javanese script has already been added to Unicode in version 5. 2.

In 2007 he was commissioned by the International Association of Coptic Studies to create a standard free Unicode 5. 1 font for Coptic, Antinoou, using the Sahidic style.

Ol Chiki script was added to the Unicode Standard in April, 2008 with the release of version 5. 1.

The Apple Type Services for Unicode Imaging ( ATSUI ) is the set of services for rendering Unicode-encoded text starting with Mac OS 8. 5 and in OS X.

ATSUI was replaced by a more robust and modern Unicode imaging engine called Core Text in OS X 10. 5 ( Leopard ).

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.

In Unicode, it is encoded at.

A proposal was posted by Michael Everson for the Blissymbolics script to be included in the Universal Character Set ( UCS ) and encoded for use with the ISO / IEC 10646 and Unicode standards.

BCI would cooperate with the Unicode Technical Committee ( UTC ) and the ISO Working Group.

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.

* Michael Everson's First proposed encoding into Unicode and ISO / IEC 10646 of Blissymbolics characters, based on the decomposition of the ISO-IR / 169 repertoire.

In particular, the Unicode standard provides foundations for complete BiDi support, with detailed rules as to how mixtures of left-to-right and right-to-left scripts are to be encoded and displayed.

In Unicode encoding, all non-punctuation characters are stored in writing order.

Such Unicode control characters are called marks.

BeOS used Unicode as the default encoding in the GUI, though support for input methods such as bidirectional text input was never realized.

Numeric references always refer to Unicode code points, regardless of the page's encoding.

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.

The proper glyph is in the Unicode standard at code point A792.

* 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.

A standard algorithm for collating any collection of strings composed of any standard Unicode symbols is the Unicode Collation Algorithm.

For example, " Figure 7b " goes before " Figure 11a ", even though ' 7 ' comes after ' 1 ' in Unicode.

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.
