utf-7as you might already know utf-7 is not a supported java (and hence cf) charset. it does however exist in the wild, mainly as part of bounced email systems and sometimes used in webmail like hotmail (well mainly hotmail, i've never seen it anywhere else to tell you the truth) as well as MS Exchange. folks have been complaining off and on about this for years, many mistakenly blaming macromedia for a sun java bug. votes have piled up in sun's java bugparade but alas and alack, nothing's been done about it. until now. there's a very persistent thread (its been running since feb-2004) in the cf support forums concerning this issue. a few days ago somebody (gdbezona) posted a link to an opensource utf-7 charset JCharset. if you drop that jar (jcharset.jar) into the cfinstall/runtime/jre/lib dir and stop/restart cf server ervice, cf will pick up that utf-7 charset fine. we've exercised this jar pretty thoroughly over the last two days and it has yet to blow up in our faces. it works with cfpop/cfmail/cfile and shows up in the server's available charsets via our charset CFC.
if you're experiencing this issue, you might want to give this thing a whirl.
