Support for Unicode in gcc

Support for Unicode in gcc

[ssathyan]

Hi,

I am involved in porting applications from VC++ to Linux.
I am using gcc compiler. Is there support for Unicode in gcc.

How do I specify Unicode literal strings in the source code.
For example with microsoft compiler I specify Unicode strings as.

wchar_t   *wtext = L"abc";

How do we do this in gcc?

Thank's

Sajan

Just like in VC++.  The line above compiles successfully for me with
g++.

Right. Except that VC++ generates a string with two-byte characters,
and gcc generates a string with four-byte characters.

In standards speak, you are not getting a Unicode string with the above, you
are getting a wide character string.  It just so happens on the Windows system,
that they use currently use Unicode for the wide character representation.

You didn't mention what system you are using.  Different systems have different
sizes of wchar_t.  GCC tries to conform to whatever is the local convention on
the system.
