Do the subtitles contain ASCII characters or only non-ASCII ones? If they do contain ASCII but even that is not properly displayed then it could be a problem with the font. Does the file contain embedded fonts? If so then does -noembeddedfonts change the behavior? Any further tests will be easier to do if you post a sample. If the problem occurs without using the particular embedded fonts in the file then just the subtitle track extracted with mkvextract should be enough to reproduce it.
