Trouble with normalization

[<Cha...@si...>]

Sorry to bother you guys with this, but...I'm trying to get normalization
to work.  I'm converting from an array of OLECHARs to a UnicodeString
before I do a Normalizer::normalize function.  No matter how I try it, I
keep gettng a U_STRING_NOT_TERMINATED_WARNING.  Can you help?  My code
section is below.

      UnicodeString ustIn;
      for (int cch = 0; cch < cchIn; cch++)
            ustIn += prgchIn[cch];
      UnicodeString ustOut;

      UChar uch = 18;   //these two lines put a cap that ICU code
recognizes on the
      ustIn += uch;     //string we're dealing with

      Normalizer norm(ustIn, UNORM_NFKD);
      UErrorCode ErrorCode = U_ZERO_ERROR;
      int ch = 0;

      norm.normalize(ustIn, UNORM_NFKD, 0, ustOut, ErrorCode);

Thanks,
Charley
