Replace ligature in bookmarks

I am trying to replace the s: ligature in the bookmarks by just an s. This is needed as my document is written using a fraktur font, but the colon appears inside the bookmarks as they are not in fraktur.

s:

s

My current code is the following one:

documentclass[a4paper]scrartcl usepackageyfonts addtokomafontdispositionfrakfamilyfraklines usepackage[hidelinks]hyperref usepackagexstring newcommandremoveLigatures[1]% IfSubStr#1s:% StrSubstitute#1s:s% #1 newcommandmySection[1]% sectiontexorpdfstring#1removeLigatures#1 begindocument frakfamily tableofcontents mySectionJus:t a tes:t enddocument

There seems to be some issue with my code, as I get a bookmark with the text Jus:t a tes:ts:s:sJus:t a tes:t. How can I fix this to achieve the desired results?

Jus:t a tes:ts:s:sJus:t a tes:t

You must do the replacement before feeding the argument to texorpdfstring. E.g. with expl3:

documentclass[a4paper]scrartcl usepackageyfonts usepackage[hidelinks]hyperref usepackageexpl3 ExplSyntaxOn newcommandremoveLigatures[1]% tl_set:Nn l_tmpa_tl#1 regex_replace_all:nnN s: s l_tmpa_tl newcommandmySection[1]% removeLigatures#1 sectiontexorpdfstring#1l_tmpa_tl ExplSyntaxOff addtokomafontsectioningfrakfamily begindocument frakfamily tableofcontents mySectionJus:t a tes:t enddocument

While this works for the basic case, this eliminates all colons from s::, too. Instead this should be translated to s: as inside the document text itself (where it is represented by the s: ligature followed by a regular colon). This seems to be just a little regex fix.

s::

s:

yes, sorry I forgot the s in the regex.
