Android: use Upper function for Unicode string

The user @alisichkin has the same issue as me, and I created a post https://discuss.zetetic.net/t/build-custom-android-sqlcipher-with-icu-support/5966/1 before realizing that he had already created a very similar post.

My question is:
ok i need ICU and Sqlcipher, are there a way to do a custom build with icu support ? And in this case the app could crash on Android N devices ?

Thanks and apologize for the duplicate post
