Thanks GN, understanding the difference between input tool & font is very useful.

Two followup questions:

  1. How do we know if a font is a unicode or not? (literally this was asked by a colleague engaged in traslation, and I wasn’t able to answer).

  2. When a text is added using an editor how does rendering of text work. For example, the Urdu text in one of my above posts renders differently on different devices. So, could you help understand what’s at play? Why different rendering.

Ex 1. On Ubuntu 18.04 (Chrome browser), system has better rendering unicode font.

Ex 2. On Windows 10 (Chrome browser), system has better rendering unicode font.

Ex 3. On Android (Chrome browser)

Now, I actually would like the text to be rendered as,

Ex 4. unicode font in a document-processor (in Ubuntu based machine).
urdu-in-word-processor

Is it possible/how can I achieve rendering text in fonts as shown in #4 above on metastudio?

Sorry, too many questions, but these are some questions I have been wanting clarity on.
