Hey... since i've BoP installed, my ingame text looks pretty bad.
i switched language from german to english, and i looks good again
when i remove the german lang file from the BoP archive, it looks normal also.

please fix it it isn't already fixed (Biomes-O-Plenty-0.5.7-1.5.2.zip)

using BDcraft x128

Sounds more like a problem with the texture pack. Have you tried the German language pack with vanilla textures?

i tested with complete fresh install, only forge and BoP with Vanilla Tex-pack.

the error wasn't line 2 ;)

its line ~191

<entry key="tile.bop.wood4.hellbarkWood.name">H[unicode]nrindenholz</entry>

it should be

<entry key="tile.bop.wood4.hellbarkWood.name">Höllenrindenholz</entry>

please fix in future versions :)

its now

Hönrindenholz instead of Höllenrindenholz

I'd recommend either submitting a pull request or PM'ing me on MCF with a fixed German translation. Honestly, other than remove invalid characters, there's not a whole lot i can do about spelling of things with me not knowing German.
