Hi Mike, Is this still an issue or has it been resolved? Val

Essentially, if I run normalizePath() recursively on a path that contains '�' (I haven't tried other characters) something 'changes' in the string, but I can't work out what, and it breaks a subsequent .Call() which uses the path. The example below tries to demonstrate this in a fairly concise manner. It works fine if normalizePath() is run once, but fails after it's run a second time on itself. However, change "�xample" for "example" and both instances work. Similarly, both run fine on my Linux machine with the non-ASCII character inplace. I'd be grateful if anyone else with a Windows machine could verify this behaviour, or to shed any light on what might be the difference between path1 and path2 below.
