your comment is well taken. The mail in question was probably not meant to
go to go out on this wide an alias in this form. Last I saw it, it was being
circulated among knowledgeable people to try to gather information on Unicode
support in OS's, not in order to 'publish' a list of compliant systems.

"Unicode compliant" is a term that is fraught with problems, because it is
in fact not defined anywhere in the standard. "Unicode conformant" is the
legal term, however, we should not officially use it as header on the table
below, since the consortium are not certifying conformance.

"Supports Unicode" is the informal term for attempting to be Unicode
conformant, but not implying the same guarantees that "Unicode conformant"

Unicode 'compliant' gets mistaken for Unicode 'conformant' too easily,
which is bad. The chart should be entitled

"Operating systems which support Unicode.

Finally, I believe this is true for the Windows family.

>Windows NT all yes yes
>Windows CE yes yes
>Windows 95 no some *)
>Windows 98 no some *)
>Windows 2000 yes yes

*) code set conversions and limited, low level text output

If anybody else has information on what to add here, please send it
to (not the whole list please). We are considering
posting the table on our web site.

BTW, if someone wants to sumamrize the browsers for us in the same manner
please send info to
