[BUG] Precompiled sqlite shell for windows can't open filenames with unicode chars
Try chcp 65001

SQLite shell uses utf-8 internally, but converts between it and active code page of the console when using console functions.

chcp 65001 sets active code page of the current console window to utf-8.

c:\TEMP>chcp 65001
Active code page: 65001
