A naive regex to match supplementary characters in the range U+10000–U+EFFFF produces nonsensical results:
jshell> Pattern.matches("[\u10000-\uEFFFF]+", "abc")
==> true
Likewise the version using regex escapes rather than character escapes:
jshell> Pattern.matches("[\\u10000-\\uEFFFF]+", "abc")
==> true
