Problems with copy code from forum

[goetz]

When I copy the code of a code snippet in the forum (eg the second comment in "this thread":http://developer.qt.nokia.com/forums/viewthread/1960/#8968) and paste it into an editor (vi, MacVim, Qt Creator) and compile the stuff, I get the following error messages:

It seems that there is a problem with some special html chars.

I'm on a Mac using Safari 5.

We are looking into it.

Hi Volker,

I tried and not able to reproduce it in linux (Kubuntu) with firefox

Linux dosen't says if there are some special chars added.

I will again try it on mac.

If you have some more information to reproduce it then please let us know.

On a mac I get this, when I paste the copied text to hexdump:

@
volker@macpro ~ $ hexdump -C
    QApplication app( argc, argv );
00000000 c2 a0 c2 a0 c2 a0 c2 a0 51 41 70 70 6c 69 63 61 |........QApplica|
@

instead of 20 for the spaces there is c2 a0 in the copied text, which are the UTF-8 bytes for non-breaking space ( &#160; ).

The HTML source code does only contain regular spaces, I think something is going on with the syntax highlighter or it is a Mac/Safari specific bug, since on Arora I do not get this strange conversion.

[gurudutt]

I just tested it in mac and safari here again with hexdump -C command
and I am not getting c2 a0

I will do more testing and if I will get something here then will try to fix it.
