No idea of why the problem but I can confirm it. I get the same error message in 2.0.6 and 2.1 dev with what seems to be the same Ubuntu/TexLive setup.

The only background information I've read is: http://wiki.lyx.org/LyX/XeTeX Is there anything else I should read? I'm using Ubuntu 13.04 and TeX Live 2013. With LyX 2.0.x and 2.1git I cannot export the Math manual to PDF with XeTeX. 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} Any ideas? Scott
