Fully re-implemented from scratch and an original work, this UTF-8 encoder does not rely on the traditional method of range switching in various algorithms but has just one functional while loop to build the string.
Built around this encoder are 6 utf8-printf() functions that allow printing a standard UTF32 - UNIX 32 bit wide character (wchar_t) string to stdout, a string, or a file as a UTF-8 encoded string.
Features
- Print internal UTF32 strings to UTF8 terminal output with utf8_printf() functions
- Standard printf() function integer returns plus ferror() and errno set per ISO C standards
- Handles strings up to 32MB long
- Very Small Library with a total of 70 lines of code (minus blanks and comments)
- ---
- NOTE: Compiles but throws an assertion error on execute and aborts!
- NOTE: You should never use, it's evil! Google 'buffer overflow'.
