Javascript - how to find hebrew?

JavaScript does not support regex scripts like \p{InHebrew} (or something similar). However, it does support Unicode escapes, so you could use a regex like:

/[\u0590-\u05FF]/

which will match a single Hebrew character.

See: http://unicode.org/charts/PDF/U0590.pdf and: http://www.regular-expressions.info/unicode.html

This will find hebrew letters encoded in the Hebrew Unicode code point range: [\u0590-\u05FF]
