TETRAEDGE: German umlauts are not displayed

[windlepoons]

When click on BONUS in the Syberia menu, the menu screen is missing umlauts. MEN instead of MENÜ.

The font Bulle Normal (BULLN___.TTF) included in Syberia 2 is not compatible with all German umlauts, so Comic Relief Normal was used instead for Syberia 1.
The font BULLN___.TTF available in Syberia 1 is a renamed Comic Relief Normal (ComicRelief.ttf).

Workaround

In Syberia 2 (German and other languages with Bulle font problems) ScummVM should use ComicRelief.ttf instead of BULLN___.TTF (default in Syberia 1). But ComicRelief.ttf is not an uppercase font.

For my test I renamed the font Komika Text Kaps Normal (KOMTXTK_.ttf) to BULLN___.TTF and it works.
