I think one can say that from an IETF perspective, the question is<br>whether one should allow codepoints in the Unicode table that is of<br>one or more of the following General Categories should be allowed in<br>the U-label as defined by the document edited by John:
<br><br>gc ; Sc ; Currency_Symbol<br>gc ; Sk ; Modifier_Symbol<br>gc ; Sm ; Math_Symbol<br>gc ; So ; Other_Symbol<br><br>What John says is that we who look at this problem so far have not<br>seen enough evidence that these classes really are needed so that
<br>they should be included. We are using an inclusion based algorithm<br>this time.<br><br>What it a special General Category you where thinking of Avri?<br><br> Patrik<br><br>_______________________________________________
