Summary: This project aims to privide a set of free scalable
|
||
|
|
(PostScript Type0, TrueType, OpenType...) fonts covering the ISO
|
||
|
|
10646/Unicode UCS (Universal Character Set).
|
||
|
|
|
||
|
|
|
||
|
|
Why do we need free scalable UCS fonts?
|
||
|
|
|
||
|
|
A large number of free software users switched from free X11
|
||
|
|
bitmapped fonts to proprietary Microsoft Truetype fonts, as a) they
|
||
|
|
used to be freely downloaded from Microsoft Typography page
|
||
|
|
<http://www.microsoft.com/typography/free.htm>, b) they contain a more
|
||
|
|
or less decent subsed of the ISO 10646 UCS (Universal Character Set),
|
||
|
|
c) they are high-quality, well hinted scalable Truetype fonts, and d)
|
||
|
|
Freetype <http://www.freetype.org/>, a free high-quality Truetype font
|
||
|
|
renderer exists and has been integrated into the latest release of
|
||
|
|
XFree86, the free X11 server.
|
||
|
|
|
||
|
|
Building a dependence on non-free software, even a niche one like
|
||
|
|
fonts, is dangerous. Microsoft Truetype core fonts are not free, they
|
||
|
|
are just costless. For now, at least. Citing the TrueType core fonts
|
||
|
|
for the Web FAQ <http://www.microsoft.com/typography/faq/faq8.htm>:
|
||
|
|
"You may only redistribute the fonts in their original form (.exe or
|
||
|
|
.sit.hqx) and with their original file name from your Web site or
|
||
|
|
intranet site. You must not supply the fonts, or any derivative fonts
|
||
|
|
based on them, in any form that adds value to commercial products,
|
||
|
|
such as CD-ROM or disk based multimedia programs, application software
|
||
|
|
or utilities." As of August 2002, however, the fonts are not
|
||
|
|
anymore available on the Web, which makes the situation clearer.
|
||
|
|
|
||
|
|
Aren't there any free high-quality scalable fonts? Yes, there are.
|
||
|
|
URW++, a German digital typefoundry, released their own version of the
|
||
|
|
35 Postscript Type 1 core fonts under GPL as their donation to the
|
||
|
|
Ghostscript project <http://www.gimp.org/fonts.html>. The Wadalab
|
||
|
|
Kanji comittee has produced Type 1 font files with thousands of
|
||
|
|
filigree Japanese glyphs <ftp:#ftp.ipl.t.u-tokyo.ac.jp/pub/Font/>.
|
||
|
|
Yannis Haralambous has drawn beautiful glyphs for the Omega
|
||
|
|
typesetting system <http://omega.cse.unsw.edu.au:8080/>. And so
|
||
|
|
on. Scattered around the internet there are numerous other free
|
||
|
|
resources for other national scripts, many of them aiming to be a
|
||
|
|
suitable match for Latin fonts like Times or Helvetica.
|
||
|
|
|
||
|
|
|
||
|
|
What do we plan to achieve, and how?
|
||
|
|
|
||
|
|
Our aim is to collect available resources, fill in the missing pieces,
|
||
|
|
and provide a set of free high-quality scalable (Type 1 and Truetype)
|
||
|
|
UCS fonts, released under GPL.
|
||
|
|
|
||
|
|
Free UCS scalable fonts will cover 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://partners.adobe.com/asn/developer/opentype/appendices/wgl4.html
|
||
|
|
# KOI8-R and KOI8-RU
|
||
|
|
# DEC VT100 graphics symbols
|
||
|
|
# International Phonetic Alphabet
|
||
|
|
# Arabic, Hebrew, Armenian, Georgian, Ethiopian, Thai and Lao alphabets,
|
||
|
|
including Arabic presentation forms A/B
|
||
|
|
# Japanese Katakana and Hiragana
|
||
|
|
# mathematical symbols, including the whole TeX repertoire of symbols
|
||
|
|
# APL symbols
|
||
|
|
etc.

A free Postscript font editor, George Williams's Pfaedit
|
||
|
|
<http://pfaedit.sourceforge.net/> will be used for creating new
|
||
|
|
glyphs.
|
||
|
|
|
||
|
|
Which font shapes should be made? As 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, a smaller subset of styles will
|
||
|
|
be made: one monospaced and two proportional (one with uniform stroke
|
||
|
|
and one with modulated) will be made at the start.
|
||
|
|
|
||
|
|
In the beginning, however, we don't believe that Truetype hinting will
|
||
|
|
be good enough to compete with neither the hand-crafted bitmapped
|
||
|
|
fonts at small sizes, nor with commercial TrueType fonts. A companion
|
||
|
|
program for modifying the TrueType font tables, TtfMod, is in the
|
||
|
|
works, though: <http://pfaedit.sourceforge.net/TtfMod/>. For
|
||
|
|
applications like xterm, users are referred to the existing UCS bitmap
|
||
|
|
fonts, <http://www.cl.cam.ac.uk/~mgk25/ucs-fonts.html>.
|
||
|
|
|
||
|
|
|
||
|
|
What do the file suffices mean?
|
||
|
|
|
||
|
|
The files with .sfd (Spline Font Database) are in PfaEdit's native
|
||
|
|
format. Please use these if you plan to modify the font files. PfaEdit
|
||
|
|
can export these to mostly any existing font file format.
|
||
|
|
|
||
|
|
TrueType fonts for immediate consumption are the files with the .ttf
|
||
|
|
(TrueType Font) suffix. You can use them directly, e.g. with the X
|
||
|
|
font server.
|
||
|
|
|
||
|
|
The files with .ps (PostScript) suffix are not font files at all -
|
||
|
|
they are merely PostScript files with glyph tables, which can be used
|
||
|
|
for overview, which glyphs are contained in which font file.
|
||
|
|
|
||
|
|
You may have noticed the lacking of PostScript Type 1 (.pfa/.pfb) font
|
||
|
|
files. Type 1 format does not support large (> 256) encoding vectors,
|
||
|
|
so they can not be used with ISO 10646 encoding. If your printer
|
||
|
|
supports it, you can use Type 0 format, though. Please use PfaEdit for
|
||
|
|
conversion to Type 0.
