This behavior is best described by the code below:
```
>>> meow = 1
>>> 'meow' in globals()
True
>>> µmeow = 1e-6
>>> 'µmeow' in globals()
False
>>> globals()['woof'] = 1

Martin Chase added the comment:
Oh, I just gave a cursory using `locals()`, and the same misbehavior is present.
A workaround, for anyone needing to assign or access unicode globals, is to use
`exec`, e.g. `exec("µmeow = 1e-6"
Martin Chase added the comment:
Ah! So then the proper code for me would be e.g.:
```
>>> globals()[unicodedata.normalize("NFKC", "µmeow")]
