There are no escape parentheses，Incorrectly matches `新建文件夹 (2)` against `新建文件夹 (2)`

picomatch@^2.2.1
Code：
const picomatch = require('picomatch');
const file1 = 'C:/Users/111/Desktop/新建文件夹 (2)/QQ图片20210204193714.jpg';
const file2 = '新建文件夹()';
const a= picomatch.makeRe(file1,{
dot: false,
matchBase: false,
nobrace: false,
nocase: false,
noext: false,
noglobstar: false,
posix: true,
strictSlashes: false
})
const a2= picomatch.makeRe(file2,{
dot: false,
matchBase: false,
nobrace: false,
nocase: false,
noext: false,
noglobstar: false,
posix: true,
strictSlashes: false
})
a1.test(file1);//false
a2.test(file2);// /^(?:新建文件夹())$/ false
Expected result: true
Actual result: false

Start with the provided picomatch.makeRe reproduction using the Chinese path and parentheses, then inspect how the pattern is converted into a regular expression. Verify the behavior for both examples and add regression coverage if the repository’s existing test structure supports it; done means the reported path matches as expected without breaking glob syntax.
