Mixing scripts (Re: Unicode versions (Re: Criteria for exceptional characters))

[Michel Suignard]

Probably another piece of info in the debate:

It shows what IE7 does on the UI side. This rule relaxing on script
mixing was to allow ASCII to be mixed with scripts where confusability
risk is low. This was done among other to allow Japanese to be mixed
with ASCII which is a common practice in Japan and quite a few other
writing system where ASCII can't be easily confused with native
characters but is also commonly mixed in brand names.
This is by no mean an endorsement of what should be done at the protocol
level. The list of 'allowed scripts' can be useful input for the ongoing
discussion.
