下面这个正则视别不了

/([\x{4E00}-\x{9FCC}])([0-9]{4}[0-9]{2}[0-9]{2}--[0-9]{4}[0-9]{2}[0-9]{2})(\d.\d*)/u

当前还没有支持 unicode flag。

不过 \x{4E00} 这是 php 的写法？

[kefengzhang]

是的,php还可以这样支持汉字:/\p{Han}+/u

这个似乎只需要把花括号去掉，就和 JavaScript 一样了，就能识别了。

Fixed in PR #164. The issue was that the lexer patterns in patterns.ts only matched \xHH (2 hex digits) and \uHHHH (4 hex digits), but the curly-brace variants \x{HHHHHH} and \u{HHHHHH} were not supported. Both characterClass and escapeSequences patterns have been updated to handle these cases.
