Why would you think that? If it is really old that may be possible, but everything halfway current and maintained should support UTF-8 by default by now, especially in the linux world. And in fact, it is working fine. I took the example from https://www.gnu.org/software/recutils/manual/recutils.html#A-Little-Example https://www.gnu.org/software/recutils/manual/recutils.html#A... and exchanged Emacs with Ämacs, and the selector works ~$ recsel -e "Title ~ '.*Ämacs.*'" -P Title books.rec GNU Ämacs Manual
