I don't know if this is a bug, but some letters like "ä, ö, etc", it shows incorrectly, in XMPlay it shows them correctly. If I did the module with OpenMPT, this does not happen, but if it is made with different trackers, this does happen (example: lennn_8-.xm, _cyclo_.xm, etc). Could it be that the tracker in which they were created did not support these types of letters?
