问题： vscode termina终端下划线不显示：
解决办法：
在vscode的 File->Preferences->Settings中找到 workbench 目录下 appenrence 中找到 Color Customizations 下面的settings.json 点击打开文件 ， 在文件末尾添加如下的内容：

    "terminal.integrated.fontSize": 16,
    "terminal.integrated.fontFamily": "Ubuntu mono"

添加完后效果如下：

{
    "editor.suggestSelection": "first",
    "vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue",
    "python.jediEnabled": false,
    "terminal.integrated.shell.linux": "/bin/bash",
    "editor.renderWhitespace": "none",
    "workbench.colorTheme": "Default Light+",
    "window.zoomLevel": 0,
    "terminal.integrated.fontSize": 16,
    "terminal.integrated.fontFamily": "Ubuntu mono"
}

亲测好用
