I'm getting the error "Improper \hyphenation will be flushed" \hyphenation{VC\_-X1\_-Specific\_-SetupProfiling\_-func}. I think thats because of the underscores and the number 1 which is not a letter. Is there a workaround for this problem?

  • Thanks! I still had the problem of the number 1 in the word. As far as I read numbers are not allowed in hyphenations, so I used \newcommand{\SetupProf}{VC\-X1\-Specific\-SetupProfiling\-func} to create a new command – Simon Rechermann Apr 07 '22 at 09:12
  • as I wrote: if you can use something in \hyphenation depends on the lccode. The default value of numbers is 0 but you can change it as you can change the value for the underscore. – Ulrike Fischer Apr 07 '22 at 09:20
  • Yes thats right. But I think in my case it's probably easier to use a \newcommand. There's a lot of overhead using a \hyphenation – Simon Rechermann Apr 07 '22 at 12:25
