-Custom encodings:
-~~~~~~~~~~~~~~~~~
-For each character you want to render write the line consisting of:
- hexadecimal Unicode character code,
- followed by whitespace,
- followed by hexadecimal number representing your encoding,
- followed by new line character.

-Example: to render a single letter `aogonek' (Unicode 0x0105) and encode
-it using iso-8859-2 encoding (0xB1), your custom encoding file will consist
-of a sigle line:
-0105 B1
+Encodings:
+~~~~~~~~~~
+You can get any encoding and any charset.
+1. If you want 8-bit charset, which is known to libc, encoded either in 8-bit
+   or Unicode (like ISO-8859-*, KOI8-*):
+   
+   Find correct encoding name using `iconv --list' (on RedHat) and use it.
+   For latin2 subtitles I would write:
+   ./subfont iso-8859-2 24 verdana.ttf
+   and for UTF-8 subtitles with latin2 charset:
+   ./subfont --unicode iso-8859-2 24 verdana.ttf
+
+2. If you want encoding not known to libc or non 8-bit (like EUC-KR):
+
+   Create file describing your charset:
+
+   For each character you want to render write the line consisting of:
+       hexadecimal Unicode character code
+       followed by whitespace
+       followed by hexadecimal number representing your encoding
+       followed by new line character
+   or (for UTF-8 subtitles):
+       hexadecimal Unicode character code
+       followed by new line character.
+
+   Example:
+       To render a single letter `aogonek' (Unicode 0x0105) and encode
+       it using iso-8859-2 encoding (0xB1), your custom encoding file will consist
+       of a sigle line:
+       0105 B1

+       or to get unicode font.desc, write only:
