I.e., the upper-case version of the German "sz" character has a loweer
code than the lower-case version?
Warning: that is a trick question, at least as I understand the German
case conventions. It may be unwise to assume that translating a string
from lower-case to upper-case can be done simply by replacing each
lower-case letter in the string with a character that's the upper-case
version of that letter.
