In case we don't hear an official word from RSI, I'll offer what I
know:
With version 3.1, the backslash notation became obsolete, and you could
now use STRING(202B) instead of "\xca". It's true that there was no
change in the documentation, which for 3.1 still describes the
backslash notation.
The explanation I got from RSI Tech Support was that, with the
inclusion of Windows support, the backslash is now commonly seen as the
directory delimiter in filenames, and the octal/hex notation had to go.
I welcome clarification if needed.
