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: |
|||

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. |
|||

|||
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. |
|||
