Up to now Valentina Studio was able to work only with UTF8/UTF16 dump files.
We have realize that we can easy plug ICU library into Valentina Studio itself, because Valentina engine and SQLite plugin already use ICU. In result, SQL Dump/Load dialogs now are able to work with dump files using any of supported by ICU encodings. This is about 220 encodings of the world.
Available in Valentina Studio v5.3
