non-breaking spaces are being rewritten to spaces

See original GitHub issue

When using collapseWhitespace:true and conservativeCollapse:true options, I’m seeing that non-breaking spaces (character code 160, represented as \u00A0 below) are being incorrectly converted to regular spaces (character code 32). This isn’t expected and can alter the presentation of the html - especially when the html is sent in an email. Some email clients such as gmail will collapse paragraphs with regular spaces.

$ node
> require('html-minifier').minify('<p>\u00A0</p>').charCodeAt(3)
160 // This is correct - a non-breaking space.
> require('html-minifier').minify('<p>\u00A0</p>',{collapseWhitespace:true, conservativeCollapse: true}).charCodeAt(3)
32 // This should be 160, a non-breaking space. Instead it's a regular space.
