Re: problems around →

we found the reason for that behaviour. a character map is included
in the xslt. we had (among 2100 others) five occurences for the
character → in there:

  ..
  <xsl:output-character string="&amp;ShortRightArrow;"
character="&#x02192;"/>
  ..
  <xsl:output-character string="&amp;srarr;" character="&#x02192;"/>
  ..
  <xsl:output-character string="&amp;rarr;" character="&#x02192;"/>
  ..
  <xsl:output-character string="&amp;RightArrow;"
character="&#x02192;"/>
  ..
  <xsl:output-character string="&amp;rightarrow;"
character="&#x02192;"/>
  ..

the correct mapping to → was ignored, → was
added instead and the result bo8o8o8 was caused by that (we need
the transformation to entity references since our mathml2eps
converting tool needs entity references).

no dtd error. no saxon error. frank error.
thanks michael, david and andrew for your kind help.
