Free Html Form Encoding

HTML character encodings help web browsers to interpret combinations of zeroes and ones into the characters that we read on web pages.

Character encoding has always been one of the most important problems of developing web pages, including forms and surveys. Due to the high variety of symbols used by the numerous languages, different character encodings from the HTML charset have to be used.

The default character encoding used in most browsers and in the HTML forms created with the 123ContactForm web form builder is UTF-8. If using this HTML form encoding does not display the special characters specific to your language, you can easily select another form encoding from the Form Setup page (after you log in on our site).
