use-Tag: Symbols with german umlauts in name are not displayed

[Ervin Peters]

Version: Inkscape 0.91 on gentoo Linux 64bit / Gnome

( media/gfx/inkscape-0.91-r3 (cdr dbus dia exif gnome imagemagick inkjar jpeg latex lcms nls openmp spell -postscript -static-libs -visio -wpg PYTHON_TARGETS="python2_7"))

Via a perl-script I create a svg.

The svg File contains a symbol:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
[...]
<symbol id="RWW_DE_TH.Pleiße-Radweg" viewBox="8.8203125 699.484375 337.046875 337.08984375">
  <g id="g27726" transform="matrix(1.1863818,0,0,1.1863818,-1.6437088,-130.41863)">
    <path d="m 8.8297243,841.6142 0,-141.875 141.8749957,0 141.875,0 0,141.875 0,141.875 -141.875,0 -141.8749957,0 0,-141.875 z" fill="#70ba47" />
  </g>
</symbol>
[...]

and further on an use tag:

[...]
<g transform="translate(0 250)">
  <use height="125" width="125" x="-500" xlink:href="#RWW_DE_TH.Pleiße-Radweg" y="0" />
</g>
[...]

Opening the svg via eog the file is displayed as expected.

Opening the svg via inkscape-0.91 this symbol is not displayed, though it appears in local symbols overview.

This issue appears to all symbols which ids contains some german characters [ÄÖÜäöüß]. Replacing the 'ß' in id above with 'ss' makes the symbol appear.

I assumed there are some charset conversion issues in interpreting the use flag id or a to restrictive id mangeling which prevents from finding and displaying the symbol.

Thanks for this nice software.
