Wikipedia heavily uses diverse scripts from numerous languages. It has adopted Unicode (UTF-8) as the "encoding" scheme for its websites. In order to view this Bangla version of Wikipedia, you need to have your computer set up to see web pages encoded in Unicode Bangla scripts. To do this, you need to have a Unicode capable browser and Unicode Bangla fonts. Modern browsers following web standards like Internet Explorer, Opera, Firefox and Safari  support viewing Bangla scripts once you install the necessary fonts and enable unicode support in your operating system.
Check for existing support
The following line of text shows how your computer renders the above line:
ক + ি → কি
If the rendering on your computer matches the rendering on the image, then you have already enabled complex text support for Bangla and should be able to view text correctly in Bangla script. However, this does not mean you will be able to edit text in Bangla. To edit such text you need to install the appropriate keyboard software on your operating system.
Windows XP (Service Pack 2)
Go through the following steps:
- Download the latest version of Internet Explorer(IE6+), Opera(Opera 9) or Firefox browser(Firefox 1.5)
- Download Unicode Bangla fonts from the web and install them on your operating system; quite a few of these fonts are freely available.
- Go to control panel -> Regional and Language Options -> Language, and check the "Install files for complex scripts and right-to-left languages" option. You will need your Windows XP SP2 installer CD to install these new files.
- Install Bangla support on your browsers:
- On Internet Explorer 6: Go to Tools -> Internet Options -> General -> Languages, and add Bengali as a language.
- On Firefox 1.5: Go to Tools -> Options -> Advanced -> General -> Edit Languages..., and add Bengali as a language.
- Go to your browser's "view" menu and set the "character encoding" or "encoding" feature to: Unicode (UTF-8).
- If you want to change to a favorite Bangla Unicode font for your webpages:
- For Internet Explorer 6: Go to Tools-->Internet options-->Fonts, choose Bengali from the Language Script pulldown menu and select from one of the available Bangla fonts in your system.
- For Firefox 1.5: Go to Tools -> Options -> Content tab -> Advanced... in the Fonts and colors section. In the pop up window titled "Fonts", select Bengali from the "Fonts for:" pulldown Menu and set a Bengali font of your choice for various kinds of fields like Serif, Sans Serif, Monospace, etc. to be shown on webpages.
- For Opera 9: Go to Tools -> Preferences -> Advanced tab -> Fonts>International fonts>choose Bangla from drop down list. Select Bangla font of your choice. In most of the cases,opera automatically detects your support for Unicode once you have it in operating systems and installed fonts. So, you may not require the steps above.
- Go to Start -> Control Panel -> Regional and Language Options -> Language, and check the option “Install files for complex scripts and right-to-left languages" and insert Win XP CD in your CD-ROM drive to install the files.
