This is more an issue with processing UTF-16. If you always work at
the scalar for validation the issue goes away. This is obvious, but
it's important to blur the character vs. encoding issue.
As characters, surrogate pairs have fewer issues than combining
sequences for display (or certainly no extra issues).
