Securecrt in Linux Vim displays UTF-8-encoded file garbled characters

Remember to keep it in mind. The following method does not need to change the securecrt configuration, so it does not affect the display of other Chinese characters.
Problem:
For example, if a file is UTF-8 encoded, the file header is:
1 #! /Usr/bin/ENV Python
2 #-*-coding: UTF-8 -*-
At this point:
Run securecrt to Linux and run Vim. The Chinese characters are garbled.

View securecrt-> session options
Terminal-> appearance: character encoding: Default

Solution:
You only need to run a line of command below Vim in Linux
: Set encoding = UTF-8 termencoding = GBK

No problem with displaying Chinese characters.

However, if you change the file, there will be a problem when saving it. The prompt is "Conversion error"
Add another line
: Sets fileencoding = UTF-8

To sum up, if you edit a UTF-8 file, run the following command in VIM:
: Set encoding = UTF-8 termencoding = GBK fileencoding = UTF-8
