qtmoko keyboard svg limitations

[robin]

hi,

I have just noticed that not everything I can produce in inkscape by
entering a unicode value will also be displayed when using the same
code to produce a keyboard layout. examples are arrows, ellipses triangles 
and paths. (U+2190 ← e2 86 90 LEFTWARDS ARROW)
If anyone has managed to overcome this lack please let me know (ps
radek solved this by aligning rectangles in the manner of paths
which works, but at the same time is a lot of work as well ...)
