how can I label a plot (e.g axes) with special characters like the german "ä, ö, ü" or like "°C" (degree celsius). The wxT-macro doesn't seem to work.
Looking at examples 26 or 24 I would expect that you need to use UTF-8 strings to reach your goals. The wxWidgets driver can display unicode symbols, since example 24 or 26 are working correctly. At least for the degree sign there is a work around in using symbols (run example 7), one of the available symbols must be a degree sign, which can be used in strings with some markup code, look at the manual.
PS: It may be a good idea to use the mailing list (plplot-general), since the forums are mainly monitored only by me, and on the mailing list you might get more help from the other developers as well.
