sanitize-xml-string

Not all UTF-8 characters are valid in XML. This module offers two methods, sanitize and validate, that treat a given string and prepare it for use with XML. Valid characters were taken from https://www.w3.org/TR/xml11/#charsets, which includes any Unicode character, excluding the surrogate blocks, FFFE, and FFFF ([#x1-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]).

> :warning: To deal with emoji and other special unicode use cases, ES6 added a u flag to regular expressions. This tiny module uses that flag - if you do not use ES6, you might run into where valid unicode pairs are identified as invalid individual points and thus removed.
