| Cross-platform function to stat() a file using a UTF-8 encoded name or value.
int | fl_system (const char *cmd)
| Cross-platform function to run a system command with a UTF-8 encoded string.
int | fl_tolower (unsigned int ucs)
| Returns the Unicode lower case value of `ucs`.
int | fl_toupper (unsigned int ucs)
| Returns the Unicode upper case value of `ucs`.
unsigned | fl_ucs_to_Utf16 (const unsigned ucs, unsigned short *dst, const unsigned dstlen)
| Convert a single 32-bit Unicode codepoint into an array of 16-bit characters.
int | fl_unlink (const char *fname)
| Cross-platform function to unlink() (that is, delete) a file using a UTF-8 encoded filename.
char * | fl_utf2mbcs (const char *s)
| Converts UTF-8 string `s` to a local multi-byte character string.
const char * | fl_utf8back (const char *p, const char *start, const char *end)
| Move `p` backward until it points to the start of a UTF-8 character.
int | fl_utf8bytes (unsigned ucs)
| Return the number of bytes needed to encode the given UCS4 character in UTF-8.
unsigned | fl_utf8decode (const char *p, const char *end, int *len)
| Decode a single UTF-8 encoded character starting at p.
int | fl_utf8encode (unsigned ucs, char *buf)
| Write the UTF-8 encoding of ucs into buf and return the number of bytes written.
unsigned | fl_utf8from_mb (char *dst, unsigned dstlen, const char *src, unsigned srclen)
| Convert a filename from the locale-specific multibyte encoding used by Windows to UTF-8 as used by FLTK.
unsigned | fl_utf8froma (char *dst, unsigned dstlen, const char *src, unsigned srclen)
| Convert an ISO-8859-1 (ie normal c-string) byte stream to UTF-8.
unsigned | fl_utf8fromwc (char *dst, unsigned dstlen, const wchar_t *src, unsigned srclen)
| Turn "wide characters" as returned by some system calls (especially on Windows) into UTF-8.
const char * | fl_utf8fwd (const char *p, const char *start, const char *end)
| Move `p` forward until it points to the start of a UTF-8 character.
int | fl_utf8len (char c)
| Returns the byte length of the UTF-8 sequence with first byte `c`, or -1 if `c` is not valid.
int | fl_utf8len1 (char c)
| Returns the byte length of the UTF-8 sequence with first byte `c`, or 1 if `c` is not valid.
int | fl_utf8locale ()
| Return true if the "locale" seems to indicate that UTF-8 encoding is used.
int | fl_utf8strlen (const char *text, int len)
| Return the length in bytes of a UTF-8 string.
int | fl_utf8test (const char *src, unsigned srclen)
| Examines the first `srclen` bytes in `src` and returns a verdict on whether it is UTF-8 or not.
unsigned | fl_utf8to_mb (const char *src, unsigned srclen, char *dst, unsigned dstlen)
| Convert the UTF-8 used by FLTK to the locale-specific encoding used for filenames (and sometimes used for data in files).
