Fixed by https://gerrit.libreoffice.org/c/help/+/103330 And can not confirm with 7.4 builds where the RegEx Help article [1] links to URL: https://unicode-org.github.io/icu/userguide/strings/regexp.html#regular-expression-metacharacters which resolves correctly, as does the link for Calc [2] which resolves to https://unicode-org.github.io/icu/userguide/strings/regexp.html =-ref-= [1] https://help.libreoffice.org/7.4/en-US/text/shared/01/02100001.html?&DbPAR=SHARED [2] https://help.libreoffice.org/7.4/en-US/text/scalc/01/func_regex.html?&DbPAR=SHARED
