我应该避免在变量名中使用unicode字符吗?

C#语言规范说我们可以在说明符中使用Unicode字符(类和变量名等)

The C# language specification says we can use unicode characters in specifiers (class and variable names, etc.)

我在代码中做了很长的路要走.由于我住在巴西，所以其中包含很多带重音符号的字符，并带有诸如rotação，ângulo，máximo等的变量名.

I went a long way doing this in my code. Since I live in Brazil, this includes lots of accented characters, with variable names such as rotação, ângulo, máximo, etc.

每当一个经验更丰富"的开发人员都意识到这一点时，我强烈建议您避免使用它，并将一切变回原本的状态，否则很多小猫会死掉.

Everytime a more "experienced" developers catches this, I am STRONGLY advised to avoid it and change everything back, otherwise a lot of kittens will die.

我走了很长一段路撤消，但是今天我发现在很早以前编写的方法中，仍有一些仍带有重音符号的变量，到目前为止，还没有小猫死(至少不是因为那个).

I went then a quite long way undoing it, but today I found some variables still named with accents, in methods written long ago, and no kitten died so far (at least not because of that).

由于我的语言(葡萄牙语)是重音符号，因此如果我们的代码库包含这些字符，这很有意义，因为C#明确允许它.

Since my language (portuguese) is accented, it wold make a lot of sense if our codebase has those characters, since C# explicitly allows it.

所以问题是:

是否有 sound 技术上的理由不在C#/VisualStudio代码库中使用Unicode字符?

Are there any sound TECHNICAL reason not to use unicode characters in C#/VisualStudio codebases?
