Braille Patterns : ウィキペディア英語版 | Braille Patterns
In Unicode, braille is represented in a block called Braille Patterns (U+2800..U+28FF). The block contains all 256 possible patterns of an 8-dot braille cell, thereby including the complete 6-dot cell range.〔(Unicode Chapter 15 ), section 15.10〕 ==Symbols, not letters==
In Unicode the braille characters are not defined into any script.〔 That is, the patterns are available as ''symbols'', without connection to an alphabetic letter or a number. This is because the ''same'' symbol can be used in multiple scripts, e.g. as a Latin character, a Vietnamese character, a Chinese character and a digit. For example: although represents the letter "H" in basic braille, its Unicode definition makes no reference to "H", and it is just as valid representing Korean ᄐ ''t-'', or Japanese り ''ri''. For this reason – a dot-pattern is not a letter – Unicode declares that, strictly speaking, braille patterns are 'symbols', not 'letters'. The General Property is "So" (Symbol, other), not "Lo" (Letter, other). Beyond that declaration, however, braille is treated as a script in multiple places. E.g., the character property "Script" for the 256 braille code points is ISO 15924 "Brai", for braille. This way, searching users and programs are led to the right place.
