I am experiencing a strange problem with a regular expression I have already used before. The goal is to allow the user to enter his name, with letters, hyphen, and apostrophes if needed in a php form. My regex is:
"/^[\w\s'àáâãäåçèéêëìíîïðòóôõöùúûüýÿ-]+$/i"
But... everything is allowed but the apostrophe. Escaping it will not change. Why?
To deal with unicode characters, you can do:
/^[\pN\pL\pP\pZ]+$/
where:
\pN stands for any number
\pL stands for any letter
\pP stands for any punctuation
\pZ stands for any space
It matches names like:
d'Alembert
d’Alembert (note the different apos from above)
Jean-François
O'Connors
