===Managing Chillu Charaters===
Default Karthika font available in windows for Malayalam is not able to handle [http://unicode.org/versions/Unicode5.1.0/#Malayalam_Chillu_Characters Atomic Chillu Characters] defined in Unicode 5.1.0. But current version of popular [https://sourceforge.net/projects/anjalifont/files/AnjaliOldLipiVersion%200.730.4%202008.ttf/download AnjaliOldlipi] supports atomic chillus. If you are reluctant to use fonts which are encoded with atomic chillus, and using Firefox, install [https://addons.mozilla.org/en-US/firefox/addon/7289 this] firefox extension to convert newly defined Chillaksharams to old fashion.

▲==== For Windows/IE 6 users ====
▲The older kartika unicode font supplied with windows, does not support Unicode 5.1 Atomic Chillus. So, users of Windows XP and Internet Explorer 6 should have difficulty in viewing atomic chillus in their edit box, titlebar etc. even after installing and configuring a newer Unicode 5.1 compatible malayalam font. '''Uninstalling Kartika.ttf font''' and '''configuring the user interface elements (such as Window title, icon etc) to use any Unicode 5.1 compatible font (such as Anjali/Rachana)''' through Display properties in control panel will fix this problem. Use Controlpanel->Display->Appearance->Advanced option for this configuration. Snapshot of this configuration is given [http://sites.google.com/site/vssun9/cpl.JPG here]. A snapshot of wikipedia editor after this configuration can be seen [http://sites.google.com/site/vssun9/iess.JPG here]. Here ൽ in mangal pandey is atomic.
