The TLF font format is used by TOIlet and is very similar to the FLF
font format, the only difference being the presence of UTF-8 encoded
Unicode characters. This patch adds TLF support to FIGlet if TLF_FONTS
is defined in Makefile.
When TLF_FONTS is defined, the internal character format is changed
to UCS-4 wide characters. System requirements are support to UTF-8
multibyte encoding, a font capable of displaying Unicode glyphs and an
implementation of C99 wchar.h.
Warning: UTF-8 characters are allowed as endmarks and sub-characters, but
not as a hardblank symbol.
Example:
$ fortune | ./figlet -fpagga
