/^[\u0391-\uFFE5\.\-\,\(\)]*$/
Sorry, new to regex. Had done this to allow only Chinese character.
Then after i Changed
/^[\u0391-\uFFE5\.\-\,\(\)(N/A)]*$/
Then it allows all Chinese character + A,NA, AN, N/A, A/N tried to change (N/A), (N/A),(N(/)A) yet all return the same result...
how if i wan only chinese character and exactly "N/A" only??
