ec fonts

from Wikipedia, the free encyclopedia

The ec fonts - ec stands for European Computer Modern or Extended Computer Modern - are an extension of Computer Modern to cork coding . They were implemented in Metafont by Norbert Schwarz and Jörg Knappen and are free software. The ec fonts are supplemented by the tc fonts - tc stands for Text Companion - currently (March 2005) 128 additional symbols.

history

In 1990, at the TUG conference in Cork, the T1 coding for (almost) all European languages ​​with Latin script was adopted as the new standard for LaTeX . The ec scripts should serve as a reference implementation of this coding.

Initially, prototypes were developed under the name dc fonts . the releases 1.0 and 1.1 were coordinated by Norbert Schwarz ( Ruhr University Bochum ). The releases 1.2 and 1.3 as well as the release of the ec fonts were coordinated by Jörg Knappen, who also developed the tc fonts.

Differences between the Computer Modern fonts and the ec fonts

The ec fonts come in more design sizes than the Computer Modern fonts. The design sizes of the ec fonts are: 5, 6, 7, 8, 9, 10, 10.95, 12, 14.4, 17.28, 20.74, 24.88, 29.86 and 35.83 point . The sans serif fonts cmss and ecss differ significantly; With large font sizes, ecss is considerably leaner.

While the cm fonts only have one shape for the accents, the ec fonts have different accents for lowercase and uppercase . The accents for the capital letters are flatter.

The shapes of the individual characters differ; this applies above all to the ß , § and the italic æ , but also to umlauts and other accented letters.

The tc fonts

The tc fonts are loaded into LaTeX by the textcomp package . They contain many different characters: currency symbols (including the euro ), copyright and copyleft , a minus sign, all symbol characters from ISO 8859-1 (Latin-1), old style figures and many others.
