This just deal with the transferring but not content of character coding. Problem of which should be your reader.

So, your folders on the IMAP server have non-Latin characters and listing them throws an error?

Yes, the server contains simplified Chinese and traditional Chinese, they can be displayed normally, javax.mail. It also works

[karastojko]

It is the feature I have never tested. Let me try it. Maybe I can easily add it as a new feature.

[YZJClear]

Looking forward to your updates

[YZJClear]

It doesn't look like any coding, how should i handle that it should be Chinese characters

[tsurumi-yizhou]

The character coding should be automatically recognized by your reader from MIME.

你知道怎么解决吗

IMAP folders may be UTF7 encoded which is not currently supported by mailio. Thus, it is not a bug but the missing feature.

Hello, I have two questions. First, do you have plans to add this feature? Second, are you Chinese? (I'm Chinease)

[karastojko]

I would have to check for a UTF-7 encoding C++ library, does it exist with MIT license or I should create such utility. Also, I need to see whether UTF-8 is also being used for this purposes. So, right now I do not have the straight-forward answer to your question.
Regarding the nationality - I am not Chinese.

Thank you, I will try the method you mentioned in the future.
