### Current Issue
When searching for pages using the "@" prefix, accented characters are not properly handled in the search results.
### Concrete Example
  • A page named "Téléphérique" exists in the system
  • Searching with "@Téléphé" returns no results
  • Searching with "@Telephe" (without accents) works and finds the page
### Expected Behavior
The search system should:
  • Properly recognize and handle accented characters
  • Return relevant results regardless of the presence of accents in the query
### Impact
Users cannot easily find pages containing accented characters, particularly affecting content in French and other languages that use accents.
### Steps to Reproduce
  1. Create a page with an accented title (e.g., "Téléphérique")
  2. In another page, try to create a link by typing "@Téléphé"
  3. Observe that the page doesn't appear in the results
  4. Try with "@Telephe" to confirm that the page exists
