How to decide length when working with UTF-8 in PHP + MYSQL
<p>We are developing website based on the multilingual concept. we have set the character set as UTF8 in database field. but, my question is " How to decide length when working with UTF-8"? what is the ideal way to define UTF8 in database and what should be the length of it? </p>

<p>For example, on admin side there will be a CMS page module where admin can enter content based on the language section option. let say, I have set the content field length(10) into the database table and on back-end side, Admin will select the "French" language and save the content. 
There can be different language section options. If admin will enter data in plan text then will it be stored in database with given length and character set for selected language?</p>

<p>Please do needful on this.</p>
