+                          GNU FreeFont
+
+The GNU FreeFont project aims to provide a useful set of free scalable
+(i.e., OpenType) fonts covering as much as possible of the ISO 10646/Unicode
+UCS (Universal Character Set).
+
+Statement of Purpose
+--------------------
+
+The practical reason for putting glyphs together in a single font face is
+to conveniently mix symbols and characters from different writing systems,
+without having to switch fonts.
+
+Coverage
+--------
+
+FreeFont covers the following character sets
+
+* ISO 8859 parts 1-15
+* CEN MES-3 European Unicode Subset
+  http://www.evertype.com/standards/iso10646/pdf/cwa13873.pdf
+* IBM/Microsoft code pages 437, 850, 852, 1250, 1252 and more
+* Microsoft/Adobe Windows Glyph List 4 (WGL4)
+  http://www.microsoft.com/typography/otspec/WGL4.htm
+* KOI8-R and KOI8-RU
+* DEC VT100 graphics symbols
+* International Phonetic Alphabet
+* Arabic, Hebrew, Armenian, Georgian, Ethiopian and Thai alphabets,
+  including Arabic presentation forms A/B
+* mathematical symbols, including the whole TeX repertoire of symbols
+* APL symbols
+  etc.
+
+Editing
+-------
+
+The free outline font editor, George Williams's FontForge
+<http://fontforge.sourceforge.net/> is used for editing the fonts.
+
+Design Issues
+-------------
+
+Which font shapes should be made?  Historical style terms like Renaissance
+or Baroque letterforms cannot be applied beyond Latin/Cyrillic/Greek
+scripts to any greater extent than Kufi or Nashki can be applied beyond
+Arabic script; "italic" is really only meaningful for Latin letters. 
+
+However, most modern writing systems have typographic formulations for
+contrasting uniform and modulated character stroke widths, and have some
+history with "oblique", faces.  Since the advent of the typewriter, most
+have developed a typographic style with uniform-width characters.
+
+Accordingly, the FreeFont family has one monospaced - FreeMono - and two
+proportional faces (one with uniform stroke - FreeSans - and one with
+modulated stroke - FreeSerif).
+
+To make text from different writing systems look good side-by-side, each
+FreeFont face is meant to contain characters of similar style and weight.

+
+
+Files and their suffixes
+------------------------
+
+The files with .sfd (Spline Font Database) are in FontForge's native format. 
+Please use these if you plan to modify the font files.
+
+TrueType fonts for immediate consumption are the files with the .ttf
+(TrueType Font) suffix.  These are ready to use in Xwindows based
+systems using FreeType, on Mac OS, and on older Windows systems.
+
+OpenType fonts (with suffix .otf) are for use in Windows Vista. 
+Note that although they can be installed on Linux, but many applications
+in Linux still don't support them.
