That's because this information isn't in the font in the unicode platformid, 
{-}which is the only one we consider{-}. We do support other platformIDs but 
only the 1033 languageID. Note the missing "1" nameID in the first series. The 
2nd series has a "1" but it has a unusual language value. I tried to hard-code 
it -but got junk so that's a deeper problem- then we get the correct text (I 
was confused by my IDE).
