Bad support for emoji

[sumneko]

see https://microsoft.github.io/language-server-protocol/specifications/specification-3-17/#textDocuments
The offsets should be based on a UTF-16 string representation, however this extension used UTF-8.
The length of emoji in UTF-16 is 2 while in UTF-8 is 1, which makes incorrect offsets calc.

似乎是昨天更新后才出现这样的问题？现在输入中文注释或者想往控制台输出中文，vscode就会有弹窗报以下错误

可以提供一些演示吗，我这边没法再现

[lilystudent2016]

就像这样光标在中文上就弹窗报错，Request textDocument xxx failed

[sumneko]

我yiran依然无法重现，你能弄一个可以重现的最小演示代码发给我嘛？

[lilystudent2016]

确实有点奇怪，复制单文件到新路径用vscode打开，也会出现这个弹窗报错但不在同一个地方。目前试验发现是中文的？号处会报错，不知道能否复现。
还是不能复现可以试试这个文件https://github.com/lilystudent2016/QSanguosha-For-Hegemony-Qt6/blob/75af89280c1ce3cb655915e7288471f462ff75f7/lua/ai/power-ai.lua

在中文标点符号处可以再现，谢谢！
