OK, I applied your patch. I cannot really test with the old style font mechanism, because TeX did not install any Pandora fonts on my system (I hard copied them, so they are only recognized by the new font system). It seems that the Pandora fonts use the EC encoding except for the range 0 until 31, where they follow the CM encoding. Well, all this is really exotic and deprecated, but I applied your patch; thanks.

Select Document->Program font->Pandora and open a scheme session. Type an accented letter, like á ä ö. The letters displayed are ok, but the overlayed accents are not («, instead of ´ for instance).

The font rules for Pandora fonts in fonts-ec.scm say they are CM instead of EC. This results in find_font() instantiating them via tex_cm_font(). As a result typesetting of accented characters happens using CM_accents[] and CM_unaccented[], which I think follow the OT1 font encoding (see ftp://ftp.dante.de/pub/tex/macros/latex/doc/encguide.pdf ).

However, the proper encoding for whatever font is actually used seems to be T1 (sloppily checked changing the character codes in CM_accents[] to follow T1, i.e \01 instead of \23, for the acute accent, etc.)

The attached patch changes the font rules for Pandora. Because I'm not sure the problem is not due to the lack of a particular font in my system or some weird side-effect thereof, I cannot commit until someone knowledgeable gives some input.
