回复：为什么Gmail信箱里的中文不能正确显示，哪位有解决的办法？

Although the Gmail interface is written in US English, Gmail users can send and receive messages in a variety of languages.
Right now it is only possible to search in English. All information in the 'Settings' section of your account, including your name, labels and filters must also be in English.

If you are having trouble sending or receiving messages in a language other than English, there may be two problems:

Some users have experienced problems with the following languages and encodings:
Simplified Chinese (HZ & GBK)
Cyrillic/Ukrainian (KOI8-U)
Vietnamese (TCVN)
Hebrew (ISO-8859-8-I)
Nordic (ISO-8859-10)
Armenia (ARMSCII-8)
Thai (windows-874)

Messages sent to or from other email providers may be encoded in a format that causes the text of a message to be unreadable. Gmail uses UTF-8 encoding for all messages. If you are unable to send or receive messages in languages other than English, we suggest adjusting your browser's encoding settings.
Here's how to adjust the settings in Internet Explorer:
Click the 'View' menu at the top of your browser
Select 'Encoding'
Select 'Unicode (UTF-8)' from the list of options
If this doesn't improve the problem, the improper display of characters might be the result of mail clients converting encodings during the transmission of messages.
In the meantime, you can view messages properly by opening the original sent message. To view the original message, please follow these steps:

Log in to your Gmail account
Open the conversation containing the message you would like to view
Click 'More options' at the top of the message
Click 'Show original'
The Gmail team is working on a fix for each of these problems. In the meantime, if these suggestions don't work and your language isn't on the list, please let us know by clicking 'contact us' below.
