I didn't submit this as a bug report but as an enhancement request. From
usability point of view, saying that results differ but you just cannot see the
difference is not very helpful.
The exact reason I didn't submit this as an enhancement request for unittest
Benjamin Peterson added the comment:
As stated, the bug report is invalid: the repr _does_ differ, it's just not
presented that way by however you're viewing the two reprs. Distinct codepoint
sequences that look identical under certain circumstances can happen many
different ways with Unicode

Thanks for pointing out `ascii()`. Seems to do exactly what I want.
`repr()` showing combining characters would, in my opinion, still be useful to
avoid problems like I demonstrated with unittest and pytest. I doubt it's a
good idea with them to use `ascii()` i

Use ascii() in Python 3 if you want the behavior of repr() in Python 2. It
escapes all non-ascii characters.
But escaping only combining characters in addition to non-printable characters
in repr() looks an interesting idea.

Forgot to mention that this doesn't affect Python 2:
>>> a = u'hyv\xe4'
>>> b = u'hyva\u0308'
>>> print(repr(a))
u'hyv\xe4'
>>> print(repr(b))
u'hyva\u0308'
In addition to hoping `repr()` would be enhanced in future Python 3 versions,
I'm also looking for a wa
New submission from Pekka Klärck :
If I have two strings that look the same but have different Unicode form, it's
very hard to see where the problem actually is:
>>> a = 'hyv\xe4'
>>> b = 'hyva\u0308'
>>> print(a)
hyvä
>>> print(b)
hyvä
>>> a == b
False
>>> print(repr(a))
'hyvä'
>>> print(repr
