Sorry, that was my mistake. Version 2 has the space problem in 1.43,
but not in 1.44. Version 3 is introduced in 1.44 but works in a
different way and has the space problem. I don't know how well it (or
lexical cast) handles L-strings. I've brought up the space issue on
the development list, but I'm having a bit of trouble explaining it.
Until a conclusion is reached, I'd suggest using strings in program
options, and then constructing the filesystem path yourself.
