While I would not use that plugin, there are likely a number of people who would find it useful. I am wondering where this plugin would be applied. Using send to device, exporting to disc? Are you getting the title from calibre's metadata store? Correcting it in the ePub's file .opf from calibre's metadata?

The plugin Quality Check contain a action "Normalize the fields" to convert the values into their canonical form defined by the Unicode Standard, aka merge and reorders diacritics.
Certainly what you were looking for.

This sounds like a really big ask - *any* and *every* language? Isn't there something like 7,000-8,000 languages in use today?

My plugin is designed to modify the title field in the metadata managed by Calibre.
Therefore, it does not alter the imported content itself. If that were changed, Calibre would no longer be able to manage it properly.
By keeping it this way, when exporting to EPUB from Calibre, if the filename includes the metadata title field, it becomes useful for locating the desired book on devices such as tablets, and also convenient for viewer software to display titles in an orderly manner.
For example, in the case of a famous Japanese manga:
ONE PIECE 1巻
is normalized as:
ONE_PIECE1
This normalization process:
- Converts full-width alphabets into half-width alphabets
- Replaces spaces between alphabets with underscores
- Normalizes “1巻” into “1”

Thank you for introducing my plugin.
The plugin I created is not just about simple Unicode normalization.
For example, take a famous Japanese manga title:
ONE PIECE 1巻
If you only apply Unicode normalization and convert the alphabets to half-width, it becomes:
ONE PIECE 1
This state is fine within Calibre’s metadata database, but I do not want filenames with spaces when exporting to EPUB.
Although Calibre’s export settings can handle spaces, in that case it becomes troublesome to do anything more complex. For me, it is easier to manage if the metadata database itself has already been corrected in advance.

So your intention is to normalize to basically ASCII less spaces on output?

Honestly, that sounds like Calibre's Save to disk settings should already cover it:
