Could you explain how if fails exactly?

Not really =E2=80=9Ceasily=E2=80=9D unfortunately.  It depends on the APIs =
you use.

There=E2=80=99s the R6RS API from (rnrs io ports), which is supposed to
magically do line ending conversion but doesn=E2=80=99t seem to work:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (make-transcoder (utf-8-codec) (eol-style crlf))
$13 =3D #<r6rs:record:transcoder>
scheme@(guile-user)> (transcoded-port (open-string-input-port "foo\n\rbar\n=
\r") $13)
$14 =3D #<input: r6rs-transcoded-port 60725b0>
scheme@(guile-user)> (get-line $14)
$15 =3D "foo"
scheme@(guile-user)> (get-line $14)
$16 =3D "\rbar"
scheme@(guile-user)> (get-line $14)
$17 =3D "\r"
--8<---------------cut here---------------end--------------->8---

But then there are things like =E2=80=98string-tokenize=E2=80=99 that do th=
e right
thing:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (string-tokenize "foo\n\rbar\n\rbaz")
$18 =3D ("foo" "bar" "baz")
--8<---------------cut here---------------end--------------->8---

Thanks,
Ludo=E2=80=99.
