**Ulrik Vieth***Do we need a `Cork' math font encoding?*(English)- MAPS 38, 2009, 3-11
**abstract:**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 `Cork' encoding represents only one out

of several possible choices of 8-bit subsets from a much

larger repertoire of glyphs provided in fonts such as

LatinModern or TeXGyre. Moreover, recent developments of

new TeX engines are making it possible to take advantage

of OpenType font technology directly, largely eliminating

the need for 8-bit font encodings altogether. During the

entire time since 1990 math fonts have always been lagging

behind the developments in text fonts. While the need

for new math font encodings was recognized early on and

while several encoding proposals have been discussed,

none of them ever reached production quality or became

widely used. In this paper, we review the situation

of math fonts as of 2008, especially in view of recent

developments of Unicode and OpenType math fonts such as

the STIX fonts or Cambria Math. In particular, we try to

answer the question whether a `Cork' math font encoding

is still needed or whether Unicode and OpenType might

eliminate the need for TeX-specific math font encodings.- 38/02.pdf (282kb)
**Ulrik Vieth***OpenType Math Illuminated*(English)- MAPS 38, 2009, 12-21
**abstract:**In recent years, we have seen the development of new

TeX engines, XeTeX and LuaTeX, adopting OpenType font

technology for providing Unicode typesetting support.

While there are already plenty of OpenType text fonts

available for use, both from the TeX community and from

commercial font suppliers, there is little support for

OpenType math fonts so far. Ironically, it was left

to Microsoft to develop a*de facto*standard for

OpenType math font information and to provide the first

reference implementation of a full-featured OpenType

math font. In order to develop the much-needed math

support for LatinModern and TeXGyre fonts, it will be

crucially important to develop a good understanding of the

internals of OpenType math tables, much as it is necessary

to develop a good understanding of Appendix G and TeX's`\fontdimen`parameters to develop math support

for traditional TeX fonts. In this paper, we try to help

improve the understanding of OpenType math internals,

summarizing the parameters of OpenType math fonts as well

as illustrating the similarities and differences between

traditional TeX math fonts and OpenType math fonts.- 38/03.pdf (743kb)
**Taco Hoekwater***Math in LuaTeX 0.40*(English)- MAPS 38, 2009, 22-31
**abstract:**The math machinery in LuaTeX has been completely overhauled

in version 0.40. The handling of mathematics in LuaTeX

has been extended quite a bit compared to how TeX82

(and therefore PDFTEX) handles math. First, LuaTeX adds

primitives and extends some others so that Unicode input

can be used easily. Second, all of TeX82's internal special

values (for example for operator spacing) have been made

accessible and changeable via control sequences. Third,

there are extensions that make it easier to use OpenType

math fonts. And finally, there are some extensions that

have been proposed in the past that are now added to

the engine.- 38/04.pdf (206kb)
**Hans Hagen***Unicode Math in ConTeXt*(English)- MAPS 38, 2009, 32-46
**abstract:**This article is complementary to Taco Hoekwater's article

about the upgrade of the math subsystem in LuaTeX. In

parallel (also because we needed a testbed) the math

subsystem of ConTeXt has been upgraded. In this article

I will describe how we deal with Unicode math using the

regular Latin Modern and TeX Gyre fonts and how we were

able to clean up some of the more nasty aspects of math.- 38/05.pdf (297kb)
