problems with encoding

Hi,

I have a Map info file named map.TAB and when I tried to export it to
Postgres I get an error of encoding so I used konwert to convert it to utf8
using the following statement
konwert any/es-utf8 map.TAB -O

But this only convert the name of the header of each column but not the
registers of each column so I don't know what to do in order to make it work
and I get the following error

ERROR 1: INSERT command for new feature failed.
ERROR: invalid byte sequence for encoding "UTF8": 0xe17465
HINT: This error can also happen if the byte sequence does not match the
encoding expected by the server, which is controlled by "client_encoding".

Command: INSERT INTO "geocalderas" (wkb_geometry , "fnode_", "tnode_",
"lpoly_", "rpoly_", "length", "geo_lin_", "geo_lin_id", "fnode1", "tnode1",
"lpoly1", "rpoly1", "geo_lin1", "geo_lin__1", "fnode1_1", "tnode1_1",
