+FONTLOG
+Pfennig font family
+==========================
+
+This file provides detailed information on the Pfennig family of fonts.
+This information should be distributed along with the Pfennig fonts and
+any derivative works.
+
+
+Basic Font Information
+----------------------
+
+Pfennig is a sans-serif font with support for Latin, Cyrillic, Greek and Hebrew
+character sets. It contains sufficient characters for Latin-0 through Latin-10,
+as well as all modern Cyrillic scripts, the full Vietnamese range, modern Greek,
+modern Hebrew, and the Pan-African Alphabet. It supports the standard Roman
+ligatures and uses OpenType tables for diacritic placement.
+
+Pfennig supports the following Unicode ranges:
+
+Range Description Coverage
+..............................................
+U+0020-U+007F Basic Latin Full
+U+00A0-U+00FF Latin-1 Supplement Full
+U+0100-U+017F Latin Extended-A Full
+U+0180-U+024F Latin Extended-B 146/208
+U+0250-U+02AF IPA Extensions 32/96
+U+02B0-U+02FF Spacing Modifiers 18/80
+U+0300-U+036F Combining Diacritics 34/112
+U+0370-U+03FF Greek 74/134
+U+0400-U+04FF Cyrillic 214/256
+U+0500-U+052F Cyrillic Supplement 14/44
+U+0590-U+05FF Hebrew 27/87
+U+1DC0-U+1DFF Comb. Diacritic Supp. 4/43
+U+1E00-U+1EFF Latin Extended Add'l 173/256
+U+2000-U+206F General Punctuation 19/107
+U+2070-U+209F Super/Subscripts 1/42
+U+20A0-U+20CF Currency Symbols 1/26 (Euro sign only)
+U+2100-U+214F Letterlike Symbols 2/80
+U+2200-U+22FF Mathematical Operators 2/256
+U+25A0-U+25FF Geometric Shapes 1/96 (Dotted circle only)
+U+2C60-U+2C7F Latin Extended-C 5/32
+U+A720-U+A7FF Latin Extended-D 5/129
+U+FB00-U+FB06 Latin Ligatures 5/7 (all except archaic ligatures)
+
+ChangeLog
+---------
+
+2012-04-10 Added Cyrillic glyphs for Orok, Khanty, Nenets (in Unicode
+ pipeline)
+2012-04-07 Improved AE ligature and U+A78D; added a few glyphs with
+ diacritics.
+2011-09-24 Added a few African Latin glyphs; improved Cyrillic breve; major
+ spacing improvements in italics; improved TTF hints.
+2010-08-31 Further refinements of Vietnamese range in all faces.
+2010-08-04 Added several obscure African letters. Corrected some stacked
+ diacritics. Corrected proposed codepoint for H with hook.
+2010-06-23 Added modern Hebrew and Greek ranges
+2010-06-17 Added all anchors needed for diacritic attachment for
+ Pan-African to upright fonts; italic fonts are by nature unsuitable
+ for Pan-African due to stylistic clashes (e.g. between a and alpha).
+ Improved lowercase thorn in all fonts. Added dropped umlaut on A, O
+ and U in upright fonts, accessible as ss01.
+2010-06-04 Finished up requirements for Pan-African Alphabet;
+ improved Vietnamese italic & bold-italic
+2010-04-23 Completed support for all Cyrillic codepoints for modern
+ orthographies.
+2010-04-14 More glyphs: African, modern Pinyin, Amerindian
+2010-04-12 Moved non-Unicode glyphs to PUA; added a few more African
+ glyphs.
+2010-04-06 Diacritic improvement in Bold Vietnamese. Additional glyphs
+ for Skolt Sami, the Pan-Nigerian Alphabet, and various other
+ African languages.
+2010-03-31 Further spacing enhancements in non-italic. Improvements in
+ Vietnamese range in Medium to prevent excessive diacritic
+ height. Spacing improvements in italic ligatures.
+2009-09-18 Major overhaul of spacing in non-italic
+2009-08-06 Added Vietnamese range.
+2009-07-30 Kerned Latin ranges.
+2009-07-29 Added Cyrillic range.
+2009-07-24 Initial release

+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
