Is there a function to test whether a string is ascii only?

[lingvisa (Martin Min)]

I don't see it in string functions, not in APOC either.

Please confirm it and I will have to do it outside of neo4j. Those functions are very helpful though.

Have you considered

Text Functions - APOC Extended Documentation

apoc.text.clean(text)

strip the given string of everything except alpha numeric characters and convert it to lower case.

and thus something similar to

match (n:Movie) where apoc.text.clean(n.title)=n.title return n;

or is this giving you issues as well
