Certainly not (mathematics).

>>> # Py 3.4.0
>>> timeit.timeit("(s1*100 + s2)[:-1]", "s1 = 'hundred'; s2 = 'EURO'")
1.9532454724939043
>>> timeit.timeit("(s1*100 + s2)[:-3]", "s1 = 'hundred'.encode('utf-8');\
...     s2 = 'EURO'.encode('utf-8')")
0.982759184290785


There are however valid reasons to not use utf-8. It
is not really direcly tied to the intrisic coding
of the characters, but to linguistics and scriptings.
