Putting the Cork back in the bottle— Improving Unicode support in TEX
نویسنده
چکیده
Until recently, all of the hyphenation patterns available for different languages in TeX were using 8-bit font encodings, and were therefore not directly usable with UTF-8 TeX engines such as XeTeX and LuaTeX. When the former was included in TeX Live in 2007, Jonathan Kew, its author, devised a temporary way to use them with XeTeX as well as the “old” TeX engines. Last spring, we undertook to convert them to UTF-8, and make them usable with both sorts of TeX engines, thus staying backwardly compatible. The process uncovered a lot of idiosyncrasies in the pattern-loading mechanism for different languages, and we had to invent solutions to work around each of them.

Do we need a ‘Cork’ math font encoding?
The city of Cork has become widely known in the TEX community, ever since it gave name to an encoding developed at the European TEX conference of 1990. The ‘Cork’ encoding, as it became known, was the first example of an 8-bit text font encoding that appeared after the release of TEX 3.0, and was later followed by a number of other encodings based on similar design principles. As of today, the ...

However, it dates back to the 1980s and is tightly wedded to 8-bit character data and custom-encoded fonts, making it difficult to configure TEX for many complex-script languages.

The future of type is OpenType (Adobe and Microsoft’s successor to Apple’s “Royal” font technology which was licensed to Microsoft as TrueType), Unicode, and other extensions of TrueType and the Type 1 font format such as ATSUI (Apple Typographic System for Unicode Information). While TEX has been extended to support other new formats and standards such as .pdf, support for the new font formats...
