Cork encoding

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The Cork (also known as T1 or EC) encoding is a character encoding used for encoding glyphs in fonts. It is named after the city of Cork in Ireland, where during a TeX Users Group (TUG) conference in 1990 a new encoding[1] was introduced for LaTeX. It contains 256 characters supporting most west and east-European languages with the Latin alphabet.

Details[edit]

In 8-bit TeX engines the font encoding has to match the encoding of hyphenation patterns[2] where this encoding is most commonly used. In LaTeX one can switch to this encoding with \usepackage[T1]{fontenc}, while in ConTeXt MkII this is the default encoding already. In modern engines such as XeTeX and LuaTeX the Unicode is fully supported and the 8-bit font encodings are obsolete.

Notes[edit]

  1. ^ 0x18 is just a "trailing zero", used to compose or (or arbitrary smaller quantities) out of percent sign (%).
  2. ^ Dotless i and dotless j may be used to compose accented variants like i with macron (ī).
  3. ^ 0x7F is the hyphenation character (not really a soft hyphen).
  4. ^ 0xD0 is used both as Eth (Ð, U+00D0) and as D with stroke (Đ, U+0110) which might be a problem at some occasions (like copying text from PDF, hyphenation, ...)
  5. ^ 0xDF contains SS (two letters S). It allows TeX to automatically convert the German lowercase ß into the uppercase form.

Supported Languages[edit]

The encoding supports most European languages written in Latin alphabet. Notable exceptions are:

Languages with slightly suboptimal support include:
