I can't read Oriya at all so I can only guess what is wrong here, but the first thing to do is to see which paragraph composer you're using, and to try setting the composer to the World-Ready Composer (assuming you're not already).
1) Select Oriya text with the Text tool
2) Hold down Control + Alt + Shift and hit J
3) In the Justification dialog, look at the Composer setting:
You want to set it to the "World-Ready Composer" setting.
If the paragraph composer is properly set to World Ready then another thing that you can look at is the font ligatures, make sure the font applied does support ligatures and that they are turned on
I've read about Shree-Lipi many times, but I have never actually seen it in use.
It looks like you're trying to type three characters, but you're actually getting eight characters, right?
Does it type correctly in another app like MS Word?
Is there a reason you can't use your OS keyboard? I typed this using the Odia keyboard built into Windows 10:
Sorry, I couldn't figure out how to type the third character correctly. Oops!
Enable Indic language input by running the Indic Preferences.js script. From the menu bar choose Windows>Utilities>Scripts. In the Scipts window there is Indic Preferences.js under the application group - double click on it and you can now use all Indian languages, including Odia. (pl. see the screenshot)
It is best to compose in Unicode. The default Kalinga font in Windows 7 works fine. Google NOTO odia and Lohit Odia are free unicode Odia fonts and work well too,
Facing problems in ODIA typing in indesign. Cant write properly. I am using Shree-Lipi. I was trying to type KALINGA (in Odia). See the attached image result. Please help me out with a start to end procedure.
Problem - See InD1 (Text was not aligned properly)
Solution - See InD2 (After changing the composer in justification)
The *Justification Tool is really helpful.
Shortcut Key - Ctrl + Alt + Shift and hit J
It has reduce all my minor errors, cause it was not the Language (font) or Indic Language Input Tool error it was justification and text-alignment I believe, and due to that there were some grammatical error too. However this Justification Tool shortcut posted by @Joel Cherney worked like magic and all my errors are solved.
