Allow public body listing based on first letter outside US-ASCII

Under Ruby 1.8, it was previously impossible to use one of the "first
letter" alphabet links on the public body listing page if the first
letter was outside [A-Za-z] since the test for the parameter only
being a single letter wasn't aware of the possibly of multi-byte
characters.  In addition, upcasing of letters outside [A-Za-z] didn't
work because String#upcase in Ruby 1.8 isn't Unicode-aware.
This commit fixes these two problems, so that non-US-ASCII first
letter links will work under Ruby 1.8.

(Fixes #1112.)
