DESCRIPTION
unicode_category_lookup() looks up the m[blue]unicode character's categorizationm[][1]. unicode_category_lookup() returns a 32 bit value. The value's
The remaining functions implement comparable equivalents of their non-unicode versions in the standard C library, as follows:
unicode_isalnum()
- Returns non-0 for all unicode_isalpha() or unicode_isdigit().
unicode_isalpha()
- Returns non-0 for all UNICODE_CATEGORY_1_LETTER.
unicode_isblank()
- Return non-0 for TAB, and all UNICODE_CATEGORY_2_SPACE.
unicode_isdigit()
- Returns non-0 for all UNICODE_CATEGORY_1_NUMBER | UNICODE_CATEGORY_2_DIGIT, only (no third categories).
unicode_isgraph()
- Returns non-0 for all codepoints above SPACE which are not unicode_isspace().
unicode_islower()
- Returns non-0 for all unicode_isalpha() for which the character is equal to unicode_lc(3) of itself.
unicode_ispunct()
- Returns non-0 for all UNICODE_CATEGORY_1_PUNCTUATION.
unicode_isspace()
- Returns non-0 for unicode_isblank() or for unicode characters with linebreaking properties of BK, CR, LF, NL, and SP.
unicode_isupper()
- Returns non-0 for all unicode_isalpha() for which the character is equal to unicode_uc(3) of itself.
