Will this change the behavior of character groups in regular
expressions? Would myString.match(/^.$/)[0].length ever have length
2? Would it ever match a supplemental codepoint?
How would the below, which replaces orphaned surrogates with U+FFFD
when strings are viewed as sequences of UTF-16 code units behave?
myString.replace( /[\ud800-\udbff](?![\udc00-\uffff])/g, "\ufffd")
.replace( /(^|[^\ud800-\udbff])([\udc00-\udffff])/g, "\ufffd")
