unicode and UTF-8

[Lisa Ungar]

Hi,
I saw in the documentation that  in 2.4.X there is support for UTF-8 in 
the uwildmat api for the inn configuration files.

Does this mean that the inn server supports unicode character sets (UTF-8) 
within the content of the newsgroups? 

For example, could one have a newsgroup which is Japanese as well as 
English newsgroups on the same inn server?

Is it the newsreader client  that provides the ability to enter and 
display UTF-8 format from the inn server? 

Do you recommended that we upgrade from 2.3.X to 2.4.1 for UTF-8 support?

Thanks for your help,

Lisa
