I originally wrote to lyx-users because I thought I was doing something wrong but perhaps something is broken?
I get: ** WARNING ** Failed to convert input string to UTF16... and the first error in my log is: ! Undefined control sequence. l.120 \DeclareInputText {176}{\ifmmode^\circ\else\textdegree\fi} If I remove the following lines from the preamble, export with XeTeX works fine (but pdfTeX is broken): \DeclareInputText{176}{\ifmmode^\circ\else\textdegree\fi} \DeclareInputText{183}{\ifmmode\cdot\else\textperiodcentered\fi} Is this something that lib/unicodesymbols is able to address?
