We are interested in supporting UTF-8 encoded strings as field values for asian, european and american languages. We tried adding such contacts via your web GUI but the field values look messed up. We also tried using your http API to post UTF-8 data (through Apache commons httpclient, Java), but it doesn't seem to work(messed up again).
Can you give us some pointers ?
Constant Contact currently uses ISO 8859-1 encoding for all of our databases and can therefore only support those character types. Unfortunately, there are certain languages and characters that are not supported. With that being said, if you are having trouble with a specific character I would be more than happy to do some testing with this.
