中文输入乱码成问号
定制securtCRT主题时， 莫名其妙的中文输入全部变成了问号字符。
网上所有解决方案无效， 绝不可能是网上说的linux系统默认编码设置问题， securtCRT也已经设置为UTF8编码了。
反复试验， 最终才发现问题所在，原来是字体问题。
定制主题期间曾经换过字体， 然而那个字体不支持中文字符集。
具体如图， 一定要选择支持中文字符集的字体：
这个楷体支持中文字符集GB2312， 这和你的linux的utf8默认设置不冲突， 这里的GB2312是secureCRT终端的输入字符集。
这个字体就没有中文字符集的支持了， 所以你在secureCRT中输入中文时， 字符都会变成问号， 因为此时终端工具无法识别中文。
按键失效
可能的解决方案：
菜单-》全局选项-》默认会话-》终端-》仿真 选择 linux终端
推荐主题配色
配色，备份并覆盖securtCRT的Color Schemes.ini文件：
