2 * UTF-8 utility functions for DarkPlaces

10 // let them be 32 bit for now

18 // When UTF8 is disabled, every u8_ function will work exactly as you'd expect
19 // a non-utf8 version to work: u8_strlen() will wrap to strlen()
20 // u8_byteofs() and u8_charidx() will simply return whatever is passed as index parameter
21 // u8_getchar() will will just return the next byte, u8_fromchar will write one byte, ...
