Gustaf,
Yes, it's what I am saying :S.
Héctor and I just checked again, in case we were missing something, but same result. The user who runs AOLserver has LANG set to UTF-8 (we tried with both en_US.UTF-8 and es_ES.UTF-8 just in case) and still get iso8859-1 when running "encoding system" in the Tcl script of dev-support, while we get "utf-8" from tclsh. Very strange.
