I remember having seen your suggestions, and tried them; only to find that I still had an inexplicable four lines of "Wide-character" warnings in the output. This had no apparent correspondence to the tests (which were far more than four, not a one of which lacked a UTF8 character), nor to any other part of my code. Maybe I was just having a bad day and it would all magically be different if I tried it again.
Yes, until Perl runs natively on UTF8, the programmer will have to make adaptations to the code at virtually every turn. Those adaptations are not necessary at all for US-ASCII...which still seems to be the standard for computing, world-wide. Computers, and their softwares, were first invented by anglophones, and their legacy is still large. Eventually, I believe open-mindedness toward other languages will prevail, and unicode-based systems will become standard.
