Hi, I've had the desire to read (in Lua) a pattern file containing no patterns.
There's a file texmf-dist/tex/generic/hyphen/zerohyph.tex in TL2014 that contains an empty \pattern statement. However, I'm reading patterns from files provided by the hyph-utf8 package, which contain bare text patterns. That is, I need to refer to a completely empty file. But I couldn't find one in hyph-utf8. I've looked at the various null.* files in the textmf tree, but all of them contain text comments. Is there any file in TeX that is guaranteed to be empty? Best regards, Stephan Hennig
