Hi, I would like to test some hyphenation patterns with XeLaTeX (so that I can use polyglossia). When I try to compile the xelatex format by
xetex -ini -etex xelatex.ini I get a bunch of error messages ! Undefined control sequence. <argument> \UnicodeEncodingName l.6994 ...{\textzerooldstyle} \UnicodeEncodingName {\oldstylenums{0}} ? ! Undefined control sequence. <argument> \UnicodeEncodingName l.6994 ...{\textzerooldstyle} \UnicodeEncodingName {\oldstylenums{0}} ? When I continue the format is built nevertheless, but then when I try to use it I get (/usr/local/texlive/2020/texmf-dist/tex/latex/base/fontenc.sty (/usr/local/texlive/2020/texmf-dist/tex/latex/base/tulmr.fd ! Undefined control sequence. <argument> <-5.5>UnicodeFontFile {lmroman5-regular}{UnicodeFontTeXLigatures ... l.60 }{} (many lines) ! Undefined control sequence. <argument> ...tTeXLigatures }<11->UnicodeFontFile {lmroman12-bold}{UnicodeFo... l.93 }{} (That makes 100 errors; please try again.) No pages of output. Transcript written on test.log. What is the recipe to create a personalized xelatex.fmt?
