As a user, I want to have a diacritic picker as a side bar. A slider which opens on a side (next to pinboard), where I can select a letter and paste to a text. Every time I have a diacritic letter (Source, author, label, etc.), I have to switch to an external application.
The list of letters is copied from wiktionary. They cover different alphabets, but even Latin coverage will support 99% of the needs.

Historically we've closed this issue several times. Replicating functionality that is better done with platform specific app, web resource, etc. is not a priority for native functionality.
Possible solutions:
System tools (I know, these are not all equivalent and you don't like this current solution)
Create your own one-page HTML index, and load it in your browers, switch back and forth to that tab, ensuire that clicking auto-copies it to your clipboard.
Use existing websites that summarize these open in a tab/browser
