New submission from Florian Bruhin <[email protected]>:
Found mostly by accident:
>>> import email.headerregistry
>>> reg = email.headerregistry.HeaderRegistry()
>>> h = reg('Content-Disposition', 'inline; 0*²')
Traceback (most recent call last):

ValueError: invalid literal for int() with base 10: '²'
This probably happens because:
>>> '²'.isdigit()
True
>>> int('²')
