PostgreSQL copy prompt: Error:invalid byte sequence for encoding "UTF8": 0xb3

Three file formats are used for testing:

ISO-8859

NETPBM PBM Image

Ascii

if[$ (File $filename |grep-c "ISO-8859")-GT 0]
Then 
Echo "ISO-8859"Psql-C"copy $schemaname. $tbname from ' $dirname/$filename ' with (format ' csv ', delimiter ', Encoding ' iso-8859-1 ')"$dbnameelif[$ (File $filename |grep-c "ASCII")-GT 0]
Then 
Echo$format Psql-C"copy $schemaname. $tbname from ' $dirname/$filename ' with (format ' csv ', delimiter ', Encoding ' UTF-8 ')"$dbnameElsePsql-C"copy $schemaname. $tbname from ' $dirname/$filename ' with (format ' csv ', delimiter ', Encoding ' iso-8859-1 ')"$dbname

This processing occurs when the file format is ASCII, and the encoding error message will still appear halfway through copy.

Finally groping to find that no matter what format, are designated as iso-8859-1 can be processed.

Fully inclusive encoding format that can handle:

Psql-c "Copy $schemaname. $tbname from ' $dirname/$filename ' with (format ' csv ', delimiter ', Encoding ' iso-8859-1 ')" $dbnam E
