Hi Hans,
Thanks for the new composing commands. I made several tests and everything
works great.
I guess when you say something like
> \withgrave {a} == \\`{a}
you mean
\withgrave {a} == \`{a}
(this is what I tested…).
Regarding the characters æ and œ, the command \chr produces them correctly,
that is
\chr{ae} \chr{AE}
\chr{oe} \chr{OE}
produce
æ Æ
œ Œ
as expected.
If you think these commands are to stay, please tell me if they have to be on
the wiki.
Best regards: Otared
