ES2018 Unicode character class escapes are not supported in ES2015

[cyan-2048]

const SPACE_OR_PUNCTUATION = /[\n\r\p{Z}\p{P}]+/u; -> this part of code means this project only supports ES2018+

Thanks. The question is whether to document that, or to revert to the longer regexp before this commit

I feel like documenting it is enough, makes the library lightweight, and as workaround I just add a code replacer in my workflow, also https://babeljs.io/docs/babel-plugin-transform-unicode-sets-regex exists

I addressed this in #287, thanks a lot for reporting this!
