TheCSX+ Indic character set, or theClassical Sanskrit eXtended Plus Indic Character Set, is used by LaTeX to represent text used in theRomanization of Sanskrit.[1][2] It is an extension of theCSX Indic character set (but removes ÿ and the punctuation marks ¢, £, ¥, «, and »),[3][4] which in turn is an extension of theCS Indic character set,[5] and is based onCode Page 437. It fixes an issue withWindows programs, by moving á from code point 160 (0xA0) (which is problematic because it displays a regular space on Windows), to code point 158 (0x9E).
