unicode in math
Dear LyX users,
with LyX 1.6, using unicode characters other than the first block is
possible also in math mode. The character in question is either replaced
by a math-equivalent (if defined in the unicodesymbols file) or by
text in math with the text-equivalent.
This is a vast improvement over the silent failure in LyX 1.5, my thanks
go out to the relevant developer(s)!
However, there remain some inconsistencies:
* while A is typeset italic, Ä (and other accented characters) are not.
* while l is typeset italic, λ (and other Greek characters) are not.
So, the question is:
* should Ä be replaced with \A in math?
More generally: should latin-1 supplement characters for which a math
equivalent exists use this instead of a text-version?
* should λ be replaced with \lambda in math?
More generally:
* should Greek characters from the Greek and Coptic
unicode block use the math-equivalent, or
* should only Greek symbols (from Greek and Coptic and/or from
Mathematical Alphanumeric Symbols) be converted to math symbols?
and could these also show as italic in the LyX GUI?
Attached is a patch for Greek in math.

This wasn't any generic unicode character, it was a delta which is

Support for individuall unicode characters in math can be achieved easily

\DeclareUnicodeCharacter{00B7}{\ifmmode\cdot\else\textperiodcentered\fi}

Unfortunately, this fails if the character in question is the first
character in a math array or equationarray (and similar).
See attached file math-inputenc-test.lyx.
(This is usually not a problem with characters like the centered dot
(Malzeichen) or \textdegree.)
As with all common LaTeX problems, there should be a package providing
this kind of table.
There are two packages supporting unicode in math (at least partially):
1. Package ucs and its utf8x font encoding together with
\SetUnicodeOption{mathletters} in the LaTeX preamble.
+ simple, all requirements are part of TeXLive (and probabely most
other standard TeX distributions)
