Nothing major, just leftovers from the uniname test file :) .
"strings" is far too vague and general to be a meaningful directory name :) .
The test picked for a non-Unified_Ideograph character the first character after the CJK area. Unfortunately, this is precisly where the Unicode Consortium adds new characters (and in fact did). Instead, pick the first character before CJK as a sample non-CJK character.
So don't test it for being whitespace already.
