Of course it can, because there is no such problem. Whoever

thought there was never looked at the UTF-8 encoding rules.

*All* ANSI characters below 0x80 are encoded as themselves;

this includes all control characters. The UTF-8 bytes all

have the top bit set, so as ASCII would appear to be in the

range 0x80-0xFF, *never* below 0x80.
