[mkgmap-dev] Mkgmap complains about '&' in role id

Sat Jan 23 21:12:38 GMT 2010

Thanks for having a look at it.

Well ofcourse it's a crappy mapped way and the busroute is mapped wrong, 
but that should not make Mkgmap complain though ;-)

Now that you've posted the XML from the API, it shows that this is 
actually caused either by Splitter or Translit because the source osm 
file used by Mkgmap shows the '&' only (not '&amp;').

I'll do some tests to see where the '&amp;' turns into '&' in my 
toolchain, but that'll have to wait until tomorrow evening.
