Im trying to search my inbox for a collection of e-mails using their subject name. unfortunately they contain some swedish characters which are not part of ascii. im guessing thats the cause since im not getting any hits when searching for words containing these characters (åäö).

is there a way for me to work around this issue?

code example:
ImapX.MessageCollection messages = _client.Folders["INBOX"].Search("SUBJECT Bärtz", true);

Hi thesquig,

i found a solution for this issue, the code update will be available on Wednesday (24th) and I will give you more details on how to use the search command with unicode queries.

Best regards,

Good day, thesquig!

i updated the code in the repository, it contains the changes needed to allow unicode search queries.

The query Looks this way:
var subject = "Bärtz";
ImapX.MessageCollection messages = _client.Folders["INBOX"].Search("CHARSET UTF-8 SUBJECT {" + Encoding.UTF8.GetByteCount(subject) + "}\r\n" + subject, true);
If you have more questions, feel free to ask. I want to remind you that the code in the repository is pre-release, so might be unstable.

Best regards,

Hi thesquig,

great to hear it works fine! I'm planning to make another update, so you don't have to specify the charset and the number of bytes for each string yourself, this will happen automatically.

I'll let you know when the update is ready.
