Hello, I'm having trouble defining a new unicode character: 'versuch.tex' reads: \defineXMLentity [\#9633] {\symbol[8]} 'versuch.xml' reads: □ Trying to compile this like so: texmfstart texexec --environment=versuch.tex versuch.xml Yields the error below. What am I doing wrong (this works for other things like '\defineXMLentity[\#8211]{--}')? Thanks for your insights! Joh kpathsea: Running mktexmf UnicodeRegular25 !
