The error code HV00L means "unable to create execution".
This appears to have been fixed. See:-
https://github.com/tds-fdw/tds_fdw/issues/83
However, I don't follow "how" the UTF-16 data is being transformed to
UTF-8. I know that I'm thick (at times). If the SQL Server data is in
Simplified Chinese (say), how do you convert it?
Postgres handles some multi-byte codings:-
WIN932 --> SJIS
WIN936 --> GBK
WIN949 --> UHC
WIN950 --> BIG5
So you can run createdb specifying one of those encodings, lc_collate,
etc.
