text field data transfer?

I need to transfer data from pg to m$sql.
m$sql has bcp (like pg's copy). bcp use delimiter.
there are 4 ways

1) use pg's copy then m$sql's bcp:
bcp does not recognize null. so, I have to use pg's copy
with null as '' (BTW, it does not work in 6.5.1, right?)

a more serious problem is that
text field usually contains ugly-dirty charactors,
so, what is the safe delimiter? -- the key here is that
delimiter approach does not escape
within the content (for speed).

2) to solve that headache, I try to use "pg_dump -D" .
however, pg put a lot of escape there (e.g.
\015 ).

also, int8 can not be used here. -- I rechecked the design,
and change it to int4 and then dump it :-)

more seriously, m$sql is strangely sensitive to the word "exit"
(quotation mark not included) within the sql single quotation
mark! m$shit!

3) dynamically connect two db. using perl.
or, if can not connected directly, use perl write a
"pg_dump-D-like" program.

4) bcp can use fix-length format. However, seems pg's copy can not.
of course, I can write a perl to do that. but text field can not
have fixed length!

Do I have to use 3) ? is there a short cut?
