Dear John, Patrik and Harald,

I would like to ask you to remove the UTF character 03c2 (Greek small letter
final sigma) from the list of disallowed characters of the Draft “The
unicode Codepoints and IDNA draft-faltstrom-idnabis-tables-05.txt, Feb 18,
2008” and place it in the PVALID list of characters.

In previous emails I have expressed the view that by disallowing this
character you are prohibiting from registration or misrepresenting a lot of
Greek words that use this character. 

By choosing to disallow the small final sigma you are not allowing people
who use the Greek language to use the IDNs as they were originally expected
to be used – a way of representing all languages & character sets in the DNS
space. Instead you chose to propose a protocol that disallows the full use
of a European language.

Please excuse me if this is not the proper way to ask for an Internet Draft
to be changed.

Kind Regards,
