 When `sqlite_fdw` connects to a SQLite, all strings are interpreted acording the PostgreSQL database's server encoding.
 It's not a problem if your PostgreSQL database encoding belongs to Unicode family. Otherewise interpretation transformation problems can occur. Some unproper for PostgreSQL database encoding characters will be replaced to default 'no such character' character or there will error like `character with byte sequence 0x** in encoding "UTF8" has no equivalent in encoding "**"`.
