Re: Encoding issues with literal strings (C++)

They're both the same problem. I'm not sure if this is a bug or not,
but gcc is taking more than two digits to make a string literal. In
your example:
"espec\xEDficos"

Here gcc is taking the literal as 0xedf, which is out of range. The
modulo value of 0xdf is what shows up in your output. I confirmed this
behavior in gcc 3.4.4.

Again, I always thought C only uses two digits for \x escapes, so this
smells like non-conformance to me. However, you can work around it by
terminating the sequence with whitespace, or you can make it two
strings as follows:
"espec\xED""ficos"

This is valid C syntax. The compiler will concatenate these two
strings and produce the correct characters.


What I would do, is to keep my sources encoded in utf-8, and just be
sure to output the HTML with the right "Content-type:...;charset..."
and META tag.

Except that who said that the output is HTML?

If it was HTML, I'd rather encode it in HTML, and not in UTF-8;
that is, I would have written that as: espec&iacute;ficos (which
is, BTW, how I write it whenever I need to write an HTML document
containing Spanish text).

I was, in fact, considering the possibility of having my application
decode (at run-time) the literal string containing HTML entities,
or some other encoding; even URL-encoding, perhaps --- just a %
instead of a \x .

Thanks,

Carlos
