Unicode text and a suitable font make a document easier to edit and share.
Start with the right information
Use editable Bengali text instead of a picture of each paragraph. Choose a font that contains the characters you need and allow enough line spacing.
Put it into practice
Preview mixed Bengali and English lines, long names and tables. Avoid shrinking text just to fit an entire document on one page.
Check before you share
Open the exported PDF in another viewer and inspect it at a comfortable size. Check whether text selection and searching behave as expected.
