# [NTG-context] Math encoding in XeTeX

Hi,

With ConTeXt and pdfTeX you can use \enableregime[utf] (utf8 encoding) with
normal mode and math mode (no need to write \pm, \alpha or \times). But with
ConTeXt and XeTeX you don't have to specify utf8 regime, because XeTeX can
read utf8 directly. However, math mode in XeTeX is a different story ( 256
character tfm's are needed and so, and the encoding has to be ascii, so you
have to write \pm, and ± doesn't work).

It would be nice if utf8 regime (using uni-xxx files) could be enabled only
for math mode when using XeTeX, and so you would be able to input unicode
characters in all modes (normal and math).
