String Comparison Incorrect
See original GitHub issue🐛 Bug Report
When comparing the string "1.234,56 CHF" to "1.234,56 CHF" (apparently identical) Jest is coming up with not equal. It boils down to JavaScript being weird in that "1.234,56 CHF" == String("1.234,56 CHF") is apparently false.

@jeysal @cawoodm What do you think about this quick and dirty prototype using ES2018 RegExp Unicode property escapes (in Node 8 with
--harmony_regexp_propertyflag and in Node 10 without flag) to detect replacement of adjacent characters which have General_Category=Space_Separator and format the code point (if either or both are not space).There are probably some more low-hanging fruit like delete or insert of zero-width characters.
