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 ░█▀█░▀█▀░█▀█░█▀▀░▀█▀░█░█░░░█▀█░█▀▀░█▀▄░█▀▀░█▀▀░█▀█░▀█▀░░░█▀█░█▀▀ ░█░█░░█░░█░█░█▀▀░░█░░░█░░░░█▀▀░█▀▀░█▀▄░█░░░█▀▀░█░█░░█░░░░█░█░█▀▀ ░▀░▀░▀▀▀░▀░▀░▀▀▀░░▀░░░▀░░░░▀░░░▀▀▀░▀░▀░▀▀▀░▀▀▀░▀░▀░░▀░░░░▀▀▀░▀░░ ░█▀▀░█░█░█▀▀░█▀▄░█░█░▀█▀░█░█░▀█▀░█▀█░█▀▀░░░▀█▀░█▀▀░░░█▀▀░█▀▄░█▀█░█▀█░░░ ░█▀▀░▀▄▀░█▀▀░█▀▄░░█░░░█░░█▀█░░█░░█░█░█░█░░░░█░░▀▀█░░░█░░░█▀▄░█▀█░█▀▀░░░ ░▀▀▀░░▀░░▀▀▀░▀░▀░░▀░░░▀░░▀░▀░▀▀▀░▀░▀░▀▀▀░░░▀▀▀░▀▀▀░░░▀▀▀░▀░▀░▀░▀░▀░░░▀░ ░░░░░░░░░░░░░░░▀█▀░█░█░█▀▀░█▀█░█▀▄░█▀█░█▀▄░█▀▀ ░░░░░▄▄▄░▄▄▄░░░░█░░█▀█░█▀▀░█░█░█░█░█░█░█▀▄░█▀▀ ░░░░░░░░░░░░░░░░▀░░▀░▀░▀▀▀░▀▀▀░▀▀░░▀▀▀░▀░▀░▀▀▀ ░█▀▀░▀█▀░█░█░█▀▄░█▀▀░█▀▀░█▀█░█▀█ ░▀▀█░░█░░█░█░█▀▄░█░█░█▀▀░█░█░█░█ ░▀▀▀░░▀░░▀▀▀░▀░▀░▀▀▀░▀▀▀░▀▀▀░▀░▀ Signed-off-by: Claudio Matsuoka <cmatsuoka@gmail.com>
