I don't think this is your problem, but in general I think it's better
to canonicalize with lc() because it will try to undo both uppercase
and titlecase.
Since you are here ;-)
Why does ñ not uppercase to Ñ ?
Which bits of which Unicode.org files are used by uc()?
lib/unicore/To/Upper.pl includes a toupper mapping of ñ to Ñ properly.

If !SvUTF8() and C locale would be used,
uc() does not uppercase "\xF1" to any other character.
print uc(chr(0xF1)) eq chr(0xD1)
? "ok" : "not ok", " in ASCII\n"; # maybe not ok
print uc(pack('U', 0xF1)) eq pack('U',0xD1)
? "ok" : "not ok", " in utf8\n"; # of course ok
print uc(chr(0xF1)."\x{FEFF}") eq chr(0xD1)."\x{FEFF}"
? "ok" : "not ok", " with ZWNBSP\n"; # ok, it's unicodified
