SQLite upper() function Unicode

SQLite upper() function Unicode

Hello,
SQLite doesn't support unicode SQL upper() function.
My question: is there a way in UniDAC to enable it?

Example:
current: select upper('aou-äöü') -> 'AOU-äöü'
expected: select upper('aou-äöü') -> 'AOU-ÄÖÜ'


Some suggestion?

Br,
