|Hi, if I'm not mistaken, I believe that Hindi is a Unicode-only character language set, so you need to make sure that you set your HTML character set to Unicode.|
So you need to make sure that the version of Macromedia Dreamweaver that you own supports Unicode character sets. I believe that version 8 and higher supports Unicode. If so, go to the 'help' button and type in 'Hindi' to walk you through configuring Dreamweaver for your language. utf8 is a Unicode character set that will enable you to code in Hindi.
Once configured, make sure that you have a meta tag for Unicode support. If not, place in the header section between brackets (< >) this meta tag:
meta http-equiv="content-type" content="text/html; charset=utf8"
You can do this by going into 'code' view in Macromedia Dreamweaver and just typing in the HTML.
All of this assumes that your computer system set-up (hardware and software) supports Hindi.
