 Well - OGR just passes raw string trough. It's not correct, still for a
 latin letters based text it will work just fine. I made a bad example, as
 I should be using example "Rîga", which is incorrect, still for anyone in
 Latvia it would be clear that it should be "Rīga". GRASS 6.4.0 was just
 passing-through any attribute data and thus ignored any coding issues.
 Changes in 6.4.x introduced (broken by design) recoding of values and thus
 instead of just seeing broken string, that might be meaningful enough to
 be fine, now it displays error message. Saying "just set correct encoding
 in blahblah" for non-technical users equals "no attributes for You!".
 Why it's broken? Try to set encoding in preferences to datasets encoding:
