How to set up ISIS
  1. Download the ISIS package installer.
  2. Run the installer. It will set up everything by itself.
  3. Now you need to check if Windows is ready to display Indian scripts. To do so, go to Control Panel -> Regional and Language Options. Go to the Languages tab and see if the checkbox beside 'Install files for complex script and right-to-left languages (including Thai)' is checked or not. Check it if unchecked.
  4. Press the 'Apply' button. Windows will most probably want some files that are on your Windows installation disc. Enter the Windows installation cd and supply the required path in the dialog box that pops up.
  5. You may have to restart your computer.
  6. Start up Keyman from Start Menu -> Tavultesoft Keyman.
  7. You will see the Keyman icon in your system tray.
  8. Left-click on the icon to select the script you want to use.
  9. You are ready now to use any Indian script at any level of computation!

How to type using ISIS
This is a very brief and general documentation of the ISIS typing system. For detailed script-wise layouts, go here.
  • The system is phonetic in the true sense, so that's how you get the standalone consonants and vowels.
  • For long vowels, press the concerned vowel key twice.
  • To get an aspirated consonant, press 'h' after its unaspirated counterpart.
  • Try typing a vowel after a consonant.
  • Experiment with shift+<any key>.
  • To get a joined consonant (yukta varna), press '/' (once or twice) after typing the constituent consonants
  • To break up a joined consonant, press ctrl+'/'

How to set multilingual file- and folder-names

As of now, Microsoft doesn't have built-in Unicode support for three Indian scripts : Bangla, Oriya and Malayalam. So for these three scripts, the respective fonts have to be selected. Go to Control Panel -> Display -> Appearance tab -> Advanced . Select 'Icon' from the drop-down list and set the font to Rupali (for Bangla), Oriya or Thoolika Unicode (for Malayalam). Press 'OK'. Now, when you enter file- or folder-names with the keyboard layout of your choice selected in the Keyman menu the names will appear in the script you want.
For all other scripts, you do not have to go through this tedious procedure.

For a visual description of the above instructions, see here

  1. What version of Windows will I need?
    Answer: Currently only Windows 2000 and XP support non-English font dipslay using Unicode. So, that's what is officially supported. Windows 9x can handle Unicode, but not through any general and direct means.
  2. Do I need additional fonts?
    Answer: Not always. Only for Oriya, Bangla and Malayalam scripts you will be needing separate fonts which can be downloaded from the Downloads page. This is because Microsoft does not yet support these scripts ( it will do so very soon). Fonts for other scripts, if absent, can be installed from Microsoft's website, or from any Microsoft Windows or Office XP cd.
  3. Do I have to select the required font everytime I wish to type in a particular script?
    Answer: Well, yes and no. You have to select the particular fonts only for Oriya, Malayalam and Bangla (since, as stated above, Microsoft does not yet support these scripts). For all other scripts, just select it from the Keyman menu in the system tray and type on. Even if a different font is selected, your script will be correctly displayed.
  4. How do I use Indian scripts to put file and folder names?
    Answer: For Bangla, Oriya and Malayalam, you need to go to Display Properties -> Appearance -> Customise Desktop and set the 'Icon' font to the font needed for the script you want. For other Indian scripts, just select it from the Keyman left-click menu in the system tray icon, and type on!
