I have updated my e-mail plug-in to accommodate Awasu 1.1.1's support for utf-8 characters. Therefore you can now view messages in other character sets (including, for example, Western European, Chinese, Japanese, and Korean). There are a few other new features as well.
The plug-in and documentation can be found on the Awasu Web site here:
There are two different packages, but with the same functionality; which one you should use is explained on the download page.
I hope you find it useful.
