Problem Related to Unicode Text Appearance

I’m using Fedora 30 and trying to write Unicode text in Kate/KWrite, Unicode text is related to Gurmukhi script. Problem is, text editor not displaying the complete text, bottom portion of the text is not visible in these text editor but completely fine Libre Office. Is there a way to wider the line margin in kate or KWrite.

In KWrite
In Libre - Office (Correct One)
