UNICODE_UC(3) Courier Unicode Library UNICODE_UC(3) NAME unicode_uc, unicode_lc, unicode_tc, unicode_convert_tocase - unicode upper- case, lowercase, and titlecase character lookup SYNOPSIS #include <courier-unicode.h> char32_t unicode_uc(char32_t c); char32_t unicode_lc(char32_t c); char32_t unicode_tc(char32_t c); char *unicode_convert_tocase(const char *str, const char *charset, char32_t (*first_char_func)(uncode_char), char32_t (*char_func)(uncode_char)); DESCRIPTION unicode_uc(), unicode_lc(), unicode_tc() return the uppercase, lowercase, or the titlecase equivalent of the unicode character c. If this character does not have an uppercase, lowercase, or a titlecase equivalent, these functions return c, the same character. unicode_convert_tocase() takes the string str in the character set charset. first_char_func and char_func, each, should be unicode_uc, unicode_lc, or unicode_tc. unicode_convert_tocase() returns a malloc()ed buffer. The first unicode character in str gets processed by first_char_func, and all other characters by char_func.
