Ah! So then the proper code for me would be e.g.:
```

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"
New submission from Martin Chase :
This behavior is best described by the code below:
```
>>> meow = 1

False
>>> globals()['woof'] = 1

1
