JavaMail MimeMessage.getContent 不支持的编码

Question

我在使用 charset=t.101-g2

解析某种类型的邮件编码时遇到问题

我直接使用库在 Grails 中使用 JavaMail，从 IMAP 获取未读电子邮件，并尝试获取每封邮件的内容对象 msgContent = msg.getContent()

并且该行正在抛出错误。

异常

java.io.UnsupportedEncodingException: t.101-g2 [See nested exception: java.io.UnsupportedEncodingException: t.101-g2
    at java.io.InputStreamReader.<init>(InputStreamReader.java:100)
    at com.sun.mail.handlers.text_plain.getContent(text_plain.java:107)
    at javax.activation.DataSourceDataContentHandler.getContent(DataHandler.java:790)
    at javax.activation.DataHandler.getContent(DataHandler.java:537)
    at javax.mail.internet.MimeMessage.getContent(MimeMessage.java:1453)

邮件是这样的：

Content-Transfer-Encoding: 8bit
From: "Some Email" <some_email@some.com>
Content-type: text/plain; charset=t.101-g2
Subject: SomeSubject

X-Source-Args: /usr/local/cpanel/bin/autorespond some_email@some.com /home/oriental/.autorespond 
X-Source-Dir: /home/oriental

Some Text
