micromatch: Matcher doesn't work properly when glob contains Japanese characters.

Please describe the minimum necessary steps to reproduce this issue:

const { matcher } = require('micromatch')
matcher('folder/**/*')('folder/aaa.js') // => true
matcher('フォルダ/**/*')('フォルダ/aaa.js') // => false

What is happening (but shouldn’t):

See gulp#2153.

What should be happening instead?

Support glob which contains Japanese characters.
