Modx 2.8.6 and tinymce - issue with charmap, need original plugin archive

hi,

Summary

looks like I’m using since years tinymce-4.3.4-pl coming from modx 2.
I tried the new tiny mce rte (a different extentions .) that was ‘working’ but so poor (maybe many issues too I don’t know) that I turned back to my original tinymce and then things went totally bad.

Now I found the guilty is charmap plugin, not present in the system. (if I delete its name from customs plugins and customs buttons in system parameters my rte is back.
Other wise, any attempt to edit a page show errors in browser console)

essentially
assets/components/tinymce/jscripts/tiny_mce/plugins/charmap/editor_plugin.js net::ERR_ABORTED 404 (Not Found)
Tried with chat gpt to rebuild files but no success.

I need the full ORIGINAL folder content of /assets/components/tinymce/jscripts/tiny_mce/plugins/charmap/

any official archive I found are not the modx one.

thank you.

This is the official Github repository,

but the “charmap” plugin file doesn’t exist.

My guess is, that this plugin was never a part of TinyMCE 4.3.4-pl.

hmm. bad news.
Thank you

also the github you shared contains things not compatible (file are name editor_plugin.js instead of just plugin.js)..
