The Arial Unicode MS (ARIALUNI.TTF) font allows the display of characters in most languages. This font contains glyphs for all code points within the Unicode Standard, version 2.1.
NOTE: A glyph is a graphical representation of a character.
What is Unicode?
Unicode: A numeric character-encoding system that is defined by the Unicode Consortium and used by Microsoft Windows and some other computer systems.
Unicode is a 16-bit encoding that encompasses many characters that are used in general text interchange throughout the world. Each Unicode index refers unambiguously to a given character. Unicode allows a larger range of characters to be addressed than is possible by using a single-byte character encoding. All Unicode values are double-byte, which simplifies the way that a Unicode-based system reads a string of text. In comparison, a double-byte system must determine which values in a string are single-byte character codes and which are double-byte character codes.
Unicode provides a unique number for every character, regardless of which platform, program, or language is being used. For each character that is defined in Unicode, you find an assigned code point: a hexadecimal number (range 0x0000 to 0xFFFF) that is used to represent that character in computer data.
You may not find the character in what you think is the obvious place. Although the characters in Unicode are grouped into blocks, this is only a rough grouping, because characters can be categorized many different ways. In particular, punctuation and symbols are applicable across a very wide range of usages and scripts (writing systems).

The fundamental idea behind Unicode is to be language-independent, which helps conserve space in the character map. No single character is assumed to identify a language in itself. Just as the character "a" can be a French, German, or English "a", even if they have different meanings, a particular Han ideograph may map to a character that is used in Chinese, Japanese, and Korean.

Why is the file size of the Arial Unicode MS font so large?
The file size of the Arial Unicode MS font is 22 MB because it is a complete Unicode font. It contains all the characters in Arial plus full fonts for Japanese, Chinese, Korean, Arabic, and Hebrew, plus all of the different symbol characters and character ranges.
Unicode is divided into numeric ranges of similar characters. (A numeric range is a range of numerical values that are available for encoding characters.) For example, all of the Cyrillic characters are located in the same numeric range. The following ranges are included in the Arial Unicode MS font.
Spacing Modifier Letters
Combining Diacritical Marks
Latin Extended Additional
Superscripts and Subscripts
Combining Diacritical Marks for Symbols
Optical Character Recognition
CJK Symbols and Punctuation
Hangul compatibility Jamo
Enclosed CJK Letters and Months
CJK Unified Ideographs
CJK Compatibility Ideographs
Alphabetic Presentation Forms
Arabic Presentation Forms-A
Combining Half Marks
CJK Compatibility Forms
Special Form Variants
Arabic Presentation Forms-B
Halfwidth and Fullwidth Forms
NOTE: To see the specific characters that are contained in any of the ranges, follow these steps:
On the Insert menu in Microsoft Word, click Symbol.
On the Symbols tab in the Symbol dialog box, change the Subset box to the range that you want.
The Arial Unicode MS font supports characters that are defined in many different code pages. A code page is a coded character set in which each character is assigned a numeric code. Code pages are usually defined to support specific languages or groups of languages that share common writing systems. For example, code page 1253 provides the character codes that are required in the Greek writing system. Characters from the following code pages are included in the Arial Unicode MS font.
1252 Latin 1
1250 Latin 2: East Europe
1257 Windows Baltic
936 Chinese:Simplified characters
949 Korean Wansung
950 Chinese:Traditional characters
1361 Korean Johab
Macintosh Character Set (US Roman)
Windows OEM Character Set
869 IBM Greek
866 MS-DOS Russian
865 MS-DOS Nordic
863 MS-DOS Canadian French
861 MS-DOS Icelandic
860 MS-DOS Portuguese
857 MS-DOS IBM Turkish
855 IBM Cyrillic; primarily Russian
852 Latin 2
775 MS-DOS Baltic
708 Arabic; ASMO 708
850 WE/Latin 1
When should I use the Arial Unicode MS font?
The Arial Unicode MS font is intended for use when you open a document that is formatted with a different language, and you do not have the specific language font(s) installed on your computer system. If you work primarily with documents that were created in different languages, you should install the specific fonts and proofing tools for those languages.
Because of its considerable size and the typographic compromises that are required to make such a font, the Arial Unicode MS font should only be used when you cannot use multiple fonts that are tuned for different writing systems.
NOTE: It is recommended that you do not set the Arial Unicode MS font as the default font in Word.
