使用该命令将文件从 Linux 系统传输到 Google Cloud Platformgsutil cp时，在尝试处理包含未编码的非英文字符的内容（不仅仅是文件名！）时，它会在一些旧的“.eml”文件中失败统一码。
尝试的命令是：
gsutil cp "/home/darsenlu/Home/mail/Pan/Fw_ japanese_lyrics.eml" gs://darsen_backup_monthly/
错误消息是：
UnicodeEncodeError: 'ascii' codec can't encode character '\udca8' in position 22881: ordinal not in range(128)
gsutil rsync给出了一个非常相似的错误。位置 22881 (0x5961) 位于多部分电子邮件源文件的末尾。以下显示了十六进制转储文件内容：
00005960: 20a8 43a4 d1b3 a320 5961 686f 6f21 a95f .C.... Yahoo!._
00005970: bcaf 203e 2020 7777 772e 7961 686f 6f2e .. > www.yahoo.
00005980: 636f 6d2e 7477 0d0a com.tw..
我们在位置 0x5961 处看到字节“0xa8”，如错误消息所示，这是问题的根源。由于某种原因gsutil试图对文本进行编码。在支持中文字符的终端中打开文件时，我们会看到：
< 每天都 Yahoo!奇摩 > www.yahoo.com.tw
Big-5编码时，第一个汉字“-”是0xa843。一个简单的解决方法是将文件扩展名重命名为“.eml”以外的其他名称，例如“.eml.bak”，这样gsutil就不会处理文件内容。遗憾的是，在批量传输时很难提前知道是否存在这种非英文字符的文件，并且整个过程可以多次停止。
以下是完整的错误消息：
