Dear all,
Following is proposed modification to KATAKANA MIDDLEDOT definition
in tables-05 document. Excluding Alphabet and digit causes somewhat
implications to existing registration, but I couldn't find legitimate
explanation for including them as Japanese context. How to deal with
the implications is decision of registries.
Appendix A.12. KATAKANA MIDDLE DOT
Code point:
U+30FB
Overview:
MUST be used with at least one Han, Hiragana or Katakana.
Lookup:
False
Rule Set:
False;
For All Characters:
If Script(cp) .eq. ( Han | Hiragana | Katakana ) Then True;
If cp .in. U+3005..U+3007 Then True;
End For;
Best regards,
