[libxml++] UTF-8

[Fabian J. <fab...@gm...>]

Hi,

I have a problem with utf-8. I'm using personal compilation of GLibmm
2.12.10
Here is my code:

xmlpp::Document* d;
>
> d =3D new xmlpp::Document();
> xmlpp::Element* n;
>
> n =3D d->create_root_node("root","","");
>
> n->add_child("child1","");
> n->add_child("child2","");
> n->add_child("child3","");
> n->add_child("child4","");
>
> n->set_attribute("att1","valeur avec =E9 etc","");
> n->set_attribute("att2","valeur avec =EA etc","");
> n->set_attribute("att3","valeur avec   etc","");
>
> d->write_to_file_formatted("c:\\test.xml","UTF-8");
>

Remarks about output file:

   - No UTF-8 header "0xEF BB BF"
   - "=E9 etc" is coded like this "0xE9 A0 A5 74 63". I think 0x20 is
   missing for the space, I'm not sure "=E9" is correctly coded, "e" from "=
etc"
   is missing
   - "=EA etc" is coded like this "0xEA A0 A5 74 63". Same remarks
   - "  etc" is coded like this "0x20 20 65 74 63"

I tried to open the xml with explorer and I have bad characters in place of
"=E9" and "=EA".

Did I do any error in my code?

There is not need for UTF-8 files to start with these bytes, in fact it 
is very uncommon outside the MS Windows platform to have a zero width 
non-breaking space at the beginning.

Are the strings in your C code encoded using the UTF-8 character set? 
Using these string constants won't work if they are encoded in anything 
else (e.g. ISO-8859-1).

Best you would edit the C files and compile them in a locale that has 
UTF-8 at the charset. Else you either have to convert the strings to 
UTF-8 before passing them to libxml++ or store at least the character 
constants in your C file in UTF-8.

Thank you verry much.

Using Glib::locale_to_utf8("valeur avec =E9 etc"), it works fine.
