Vikas: This was fixed in GCC in 2008. The version of GCC you are using (3.4.6)

was released in 2006 and the entire 3.4.x tree is in fact from 2004. It is time

for you to upgrade your system after almost a decade if there are features you

need.

And please don't use Bugzilla for questions about using GCC, use the gcc-help

mailing list, thanks.

Hi Experts



I am facing the same kind of problem..



I had an c++ application which uses unicode string inside it, I had compiled

the solution using Visual Studio 2012. The file is saved in utf-8 with BOM(byte

order marker). When I run the same file in linux, I got the following errors:-

 error: stray '\239' in program

 1: error: stray '\187' in program

 1: error: stray '\191' in program



I found that gcc won't support BOM in the c++ file.If I remove the BOM from the

file error get resolved. Is there a way by which I can compile my application

containing files saved in utf-8 with BOM ?



I am compiling the application in Red hat enterprise Linux 4 edition , where

GCC version 3.4.6. 



Please help me in this regard.





Thanks  Regards

 Vikas

Fixed on trunk.
As I doubt this will be back-ported to 4.3.x, I am closing the bug.

I think some BOMs will be handled by iconv.
In particular I tried UTF-16 and this seemed to work ok.

UTF-8 is a special problem in two ways.  First, glibc's iconv does not
appear to recognize the UTF-8 BOM.

And, even if it did, we special-case UTF-8 (at least on non-EBCDIC hosts).

This could be fixed in files.c without too much difficulty (it makes a few
inconvenient assumptions), except that files.c does not know the name of the
source charset.

Actually I already know this is not handled.  In fact any of the BOMs are not
handled.
