When searching for specific folders in the folder section of the Library module, the search engine is generally case insensitive, except when using letters with accents.
Latest version of LRC used (13.2).
Steps to reproduce:
1. Having a folder named "Saint-Étienne" (capital E with accent)
2. Search for "étienne"
3. No result found

4. Search for "Étienne"
5. Results found
