MathType Extra Font

MT Extra Encoding

Font-family: MT Extra
Character Map:


Copyright: Copyright 1990-92 by Design Science, Inc.
  • Installed by default on Windows systems.
  • DSI is willing to allow the font to be bundled in Mozilla under the MPL license.
  • Issues: There are two versions of MT Extra (are they incompatible, i.e., with different glyph indices?). The one that exists by default on Windows systems has fewer glyphs by far than the one that comes with DSI's MathType equation editor. Unfortunately, the two versions are distributed under the same name, and so extra hard-coded detection is needed to distinguish which is which. Mozilla doesn't currently perform the detection and the MathFont Property File of MT Extra is setup using the default reduced set of glyphs. [Update this section when the complete MT Extra becomes available under the MPL.]
