That's a straight encoding problem. It seems that when regarded as "str",
you get the utf8 encoding in bytes, so ä consists of two bytes, even
though it prints as one character. Iterating over a string iterates over
the bytes. A "unicode" consists of unicode codepoints, so ä is one unit:
sage: len(u"Direct translation of 'Mäntysalo' is 'Pine forest'")
50
sage: len("Direct translation of 'Mäntysalo' is 'Pine forest'")
51
sage: print u"Direct translation of 'Mäntysalo' is 'Pine forest'"[24:26]
än
sage: print "Direct translation of 'Mäntysalo' is 'Pine forest'"[24:26]
ä
If you're going to use unicode (i.e., if you're going to use characters
that don't fit in ascii), use "unicode" objects. That's what python3 does
all the time (for strings).
