UTF32 detection routines are uniformly prefixed with mulle_utf32_is_ and
take a sole mulle_utf32_t argument. UTF16 detection routines are uniformly
prefixed with mulle_utf16_is_ and take a sole mulle_utf16_t argument.
E.g.
alphanumeric is int mulle_utf32_is_alphanumeric( mulle_utf32_t c) and
int mulle_utf16_is_alphanumeric( mulle_utf16_t c)

UTF32 character conversion routines are uniformly prefixed with
mulle_utf32_ and take a sole mulle_utf32_t argument.
The return value is mulle_utf32_t.
UTF16 character
conversion routines are uniformly prefixed with mulle_utf16_ and take
a sole mulle_utf16_t argument. The return value is mulle_utf16_t.
E.g.
tolower is mulle_utf32_t mulle_utf32_tolower( mulle_utf32_t c) and
mulle_utf16_t mulle_utf16_tolower( mulle_utf16_t c)
| Name | Description |
|---|---|
| tolower | Convert to lowercase from uppercase, returns argument, if no conversion is possible. |
