Font commands will be considered undefined if certain conditions are met.

[Meiting-Wang]

Hello Mr. Lu. I find that in the table body of tblr and longtblr environemts，\rmfamily, \bfseries, \heiti, \fangsong, and other font commands will be considered undefined if (1) they are followed by Chinese(I use package ctex to reach support for chinese), (2) I compile with xelatex or lualatex, and (3) I add the option "verb".

So this could be caused by conflicting conditions above?

Best wishes

@lvjr may be able to fix that in the package, but a simple workaround is add {}

\bfseries{}中文

works fine, it is not \bfseries that is undefined but \bfseries中文 as the space is dropped by the verb processing and 中文 are considered as letters as part of the command name. {} forces the \bfseries name to end.

@davidcarlisle Thank you for your answer, from which I know the cause of the bug and a temporary solution.

Since version 2023A, verb option was obsolete. Please use \fakeverb command from codehigh package instead.
