为高棉语制作自定义键盘布局

Question

四年前，由于医疗原因，我不得不改用 Dvorak 键盘。当时我使用的是 Windows，并自己为高棉语（我是母语）创建了一个自定义键盘布局，但现在我使用的是 Ubuntu，即使阅读了以下内容，也无法自己使用它这和这。以下是 Unicode 字符的符号代码：

default  partial alphanumeric_keys
xkb_symbols "basic" {
    name[Group1]= "Khmer (Dvorak)";

// there are four levels defined:
//
//                 normal           shift           right-alt   right-alt + shift
//

//  keys: `1234567890-=\

我对一次点击输入两个辅音有些怀疑。有些复合元音由两个独立的元音组成，但没有 Unicode 字符将它们表示为一个。Windows 似乎有一些 Unicode 字符，但它们在 Ubuntu 中不起作用，而是显示方块。不确定我是否做对了，像上面的代码一样将两个元音用空格隔开。

如果可能的话，我可以使用大写锁定切换到标准美国 Dvorak 布局，那就更好了。有谁能帮我解决这个问题？
