Would you like to check lexical form of word(s)?

Through regular expression you can check & show the alert. . ,

Regular expression will do the trick, I can write one for you if you want. Only alphabets, no numbers, no spaces, no spl characters, no apostrophe all information is needed... so update you requirement here

hi there

From my point of view you have to check each and every characters with asciicode or Unicode

Unicode is best solution.
