[mkgmap-dev] how to use diacritical marks / accents in style file

I noticed that the style file rules (sometimes?) ignore diacritical marks or accents. For instance I want to add a rule to render a bigger lakes in lower resolution, like lake Geneva: this didnt work: natural=water & name="Lac Léman" [0x3d resolution 16] only this works: natural=water & name:en="Lake Geneva" [0x3d resolution 16] Same for name:de=Neuenburgersee (works) name="Lac de Neuchâtel" (didnt work) Is there a way to use those accents in the style file rules?
