Bug reference:      2010

PostgreSQL version: 8.1 beta 4
Operating system:   Win 2000 Professional
Description:        COPY command does not recognise UTF-8 text files with
leading BOM
Details:

1) Created a UTF-8 database "foo", with a table "bar":
CREATE TABLE bar ( mycol text );

2) Used Notepad created a UTF-8 "bar.txt" text file with just the word
"fred" in it.
When writing a UTF-8 file, Notepad writes a 3-byte Byte Order Mark (BOM)
header of hex EF BB BF.
So the file's 7 hex bytes were:
EF BB BF 66 72 65 64.

This BOM header is legal - see http://www.unicode.org/faq/utf_bom.html#BOM -
but probably used only on Windows.

3) in PSQL, populated table "bar" from file "bar.txt" using:
copy bar from 'c:\\bar.txt';

4) THE BUG: postgresql doesn't recognise the EF BB BF bytes as a BOM header
and skip it.
Instead it treats the 3 bytes as a unicode character which pgAdminIII
renders as a hollow square when the table data is viewed.
That is, table data rendered as "[]fred" (where "[]" is the hollow box).

5) SUGGESTED SOLUTION: I'm not a unicode expert, so I don't know if the BOM
can be safely skipped in all cases (although it probably can for UFT-8 text
files).
But at least a COPY option SKIPBOM (or some-such).
