[Python-Dev] Unicode identifiers in test files?

[Eric V. Smith]

Is there a policy against using Unicode identifiers in test files?

As part of adding !d to f-strings, there's a code path that's only 
executed if the text of the expression is non-ascii. The easiest way to 
exercise it, and the way I found a bug, is by using an identifier with 
Unicode chars. I know we have a policy against this in Lib/, but what 
about Lib/test/?

I could work around this with exec-ing some strings, but that seems like 
added confusion that I'd avoid with a real Unicode identifier.
