Remarks​

Unicode Equality​

The definition of equality includes Unicode canonicalization. I.e. two texts are equal if they are identical after canonical decomposition. This ensures that different ways of expressing the same character in the underlying binary representation are considered equal.

'ś' . contains 's' == False 's\u301' . contains 's' == False 's\u301' . contains 'ś' == True 'ś' . contains 's\u301' == True
