about meta tag with value content-language for http-equiv attribute

[sedigh mohseni]

hi
I want to make a html page and inside of that i want to wright a few line in persian(persian is one of the rtl language)
and for that i write

<meta http-equiv="content-type" content="text/html; charset=utf8" />


but i read another form of meta and i think both of this meta tag are the same for me (i use only persian and english language in my page)

<meta http-equiv="content-language" content="en, fa" />


but later dont work for me and all line are written to persian is shown clumsy
(i konw that these two mentiond tags are diffrent but please consider i only use persian (with lang_code fa) and english , now would you please describe me what is diffrence between those only for my purpose)
in advance thanks
