Description:        ILIKE does not work with german umlauts in UTF8

Querying tables encoded UTF8 containing german umlauts such aus
Ö,ö,Ä,ä,Ü,ü with ILIKE will only return case-sensitive results. For
example:

Table:
|---------------|
|    DATA               |
|---------------|
| Österreich           |
| Niederösterreich |
| Ober Österreich  |
|---------------|

Query1= SELECT * FROM table WHERE data ILIKE '%ö%'
Result:
Niederösterreich

Query2= SELECT * FROM table WHERE data ILIKE '%Ö%'
Result:
Österreich
Ober Österreich
