Question mark

The regular expression as a string.

Most regex escape sequences just work because they are not valid Typst escape sequences. To produce regex escape sequences that are also valid in Typst (e.g. \\), you need to escape twice. Thus, to match a verbatim backslash, you would need to write regex("\\\\").
