Re: [Tinycc-devel] invalid escaped char

[Charlie Gordon]

What is the problem ?

gcc and tcc both complain about the unknown (to me also) escape string.
gcc is more cautious about not make absolute statements.  So it issues a
warning about something it doesn't know.
tcc could be a bit milder about it being "invalid" and not make that an
error...

Can you explain what this surrogate stuff is all about, and what the hell it
is supposed to mean in a C source file.

Charlie.
