special characters and \startuseMPgraphic{FunnyFrame}

[Helmut Schwertner]

Hello,

the following example does not work if the text in the 
\FrameTitle{Blockflötenspielen} contains special characters like öäßé etc.

Has someone a solution for this problem?

Thanks a lot,

Helmut

Hi Helmut,

In order to make it work you need to setup the bodyfont. Furthermore it 
is needed to let MetaPost know which font to use. See below.

Here your code gives the expected result.

I had a similar problem some time ago. But I used the utf regime. The
solution (I dont know if I read it on the list or where it came from) was
to put curly braces around those characters. In this case it would be

\enableregime[utf]
instead of
\enableregime[windows]

and then

These: Blockfl{ö}tenspielen macht Spa{ß}!

I tried this with your doc and it worked.

Probably someone soon comes up with a nicer solution,
