The algorithm2e package seems to be not compatible with LuaLaTeX. For example, compiling the following code produces an error.




Output of lualatex:

! String contains an invalid utf-8 sequence.
l.778 \renewcommand{\@algocf@procname}{Proc
! Emergency stop.

Has someone an idea how to fix that? I have a lot of algorithms typeset and do not want to switch to another package just because of LuaLaTeX.

    @Andy: converting to utf8 will help with lualatex but then you will probably get wrong fix names with pdflatex + an 8bit-option of inputenc. Using non-ascii chars in a sty is simply a bad idea. – Ulrike Fischer Nov 14 '11 at 17:33

    My version use procédure which is ok for french. A sty should be pure ascii and it doesn't matter how you save it as the result will be the same. ascii chars are encoded identically in utf8, ansinew, latin1 etc. – Ulrike Fischer Nov 14 '11 at 18:06

    @Werner please don't do that. The problem has appeared again. – Trylks Mar 8 '16 at 19:48

    Why was this question closed? I am also getting same error with lulatex, using TL 2015. How could an error from using a package in TL be off topic? – Nasser Apr 17 '16 at 2:52

algorithm2e.sty contains (at least) two non-ascii chars (é in procédure), but the file is 8bit encoded so it is not a valid utf8 file. You (or the author) should replace the é by \'e.

  • @Peter: Unfortunately there are several other usages of é in that file, so I would try to use search-and-replace. Please don't forget to post a email to the author and mentioning this. It should be fixed for the next release. – Martin Scharrer Nov 14 '11 at 16:03

    Yeah, that did the trick. Substituting all accents solved the problem. I will send an e-mail to the author. Hopefully it will be fixed in the next release. Thanks for all your help! – Peter Nov 14 '11 at 16:33
