Riched20: thanks + regression "beta" not shown

[Tobias Burnus]

Hello,

first I'd really like to thank the riched20 workers, notably Krzysztof
Foltman and Phil Krylov. For the application Diamond it made a big
difference: Instead of "[[Aring]]" etc. one sees the proper symbol and
it looks much nicer. But the biggest advantage is that one can now copy
or save the text; before the app was simply crashing when attempting to
do so.


Regression: One of the later riched20 patches, possibly
http://cvs.winehq.org/patch.py?id=16672, caused a regression with the
richedit control in Diamond.

Before it showed a beta character from the Symbol font, now it only
shows a box ("[]").

If one saves the output (rtf export) one sees

In the last line, after the \f2 (Symbol font), there should be a beta
("b" + Symbol font).

One feature request: Currently, tabs are shown as box ("[]"), how about
replacing them with a simple space - that would increase the readability
a lot. Currently, one gets (WINE-CVS):
