Ah I missed that, the original re2c regex is
[a-zA-Z_\x80-\xff][a-zA-Z0-9_\x80-\xff]*

(from https://github.com/php/php-src/blob/master/Zend/zend_language_scanner.l#L1252)

But I’m not sure about the equivalent in emacs-lisp but I know PHP does not fully support UTF-8 yet.

Is the equivalent
"[a-zA-Z_\u0080-\u00FF][a-zA-Z0-9_\u0080-\u00FF]*"
?
