Mismatch problem when series name in Comicinfo.xml uses Emoji characters only

[SteveXu9102]

What happened?

The ScannerService module seems to match emoji-characters-only series name to every other normal series name strings when reading information from Comicinfo.xml.

(By 'normal', I mean strings without emoji characters or those including both normal characters and emoji characters. )

This reproducible problem occurs when I force a scan of a Manga library, and might have caused some of my .cbz files to be abnormally ignored.

The xml files related are here: File 1 File 2 File 3 File 4

The problem may have something in common with Issue #2976.

This is because both an emoji character and a full-width dot went disappeared in a scanner output.

I guess emoji-characters-only series name string in my case became blank in the same process, and matched all other strings for some reason, which is very weird.

What did you expect?

The module should have the ability to recognize and process most UTF-8 characters in comicinfo.xml instead of deleting the uncognized ones from loaded strings.

I'll take a look at this, but let you know ahead of time it's a low priority given it seems like an edge case on top of an edge case.
