The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/11/unaccent.html
Description:

Seems a bug, because the `select unaccent('Iglésias')` result in accented
"iglésias" again... It is correct because length('Iglésias') is 9 instead
8. 

The problem is not rare as you can check by pageviews of
https://stackoverflow.com/questions/24863716  
The solution is to feed database with good UTF8 (NFC characteres).  

**SUGGESTION**:  add a notice for reders, about the aparent bug with non-NFC
input, showing examples and clues about solutions.
