Hi Jim,

Please try this patch, maybe it will help:

    "convert csz string with ^ as 'sumnik' to proper unicode string.
    Only pure ASCII strings are converted!"
    "'Mivs^ek' convertToSloveneChars"
    | in out ch |
    self class == ByteString ifFalse: [^self].
    in := self readStream. out := WriteStream on: String new.
    [in atEnd] whileFalse:

As you can see only pure ASCII strings are trying to be converted, so 
that Chinese strings won't be counted, because are TwoByteStrings already.

Well, who doesn't like to hear such a praise :) I'm specially proud that 
  Aida works for a whole world already, without much problems. And those 
problems are easy solvable. For instance, just recently we 
added/finished international Url support to Aida, see
