Find does not work for uppercase non-ASCII characters

[sigmund]

Steps to reproduce:

1. Create a file with the following content (see attachment, the file uses encoding "Text, SBCS/DBCS mode"):

Code: [Select]


æøå
ÆØÅ
2. Run "find-in-files" and search for "æ" in "<Current Buffer>".
3. The "Search Results" output is:

Code: [Select]

Find all "æ", "<Current Buffer>", "*.*", Exclude: "moc_*;ui_*;*.docx;.vs\**"
File D:\æøå
  2 1:æøå
Total found: 1     Matching files: 1     Total files searched: 14. Since this was not a case sensitive search, line 3 should also had been part of the search result.  The search result is identical if one searches for "Æ" instead of "æ".

Reproduced. Obvious typo. Called a utf-8/unicode case compare function instead of the SBCS one.

This is not hot fixable. Fixed for 24.0.2. This is a very old bug. I guess these characters are mainly seen in unicode files. Case insensitive search in unicode files works fine.

Thanks for posting this. Very good example.
