Bangla text can look correct while still being encoded incorrectly for the next tool in a publishing workflow.
Unicode stores Bengali characters in logical order and is the safer choice for websites, search, and databases. Bijoy Classic and SutonnyMJ workflows use legacy ANSI glyph positions. That means a useful Unicode-to-Bijoy converter needs more than a lookup table: it must account for pre-kar signs, reph, hasanta, conjuncts, punctuation, digits, and the visual order expected by the destination font.
A practical verification checklist:
Keep the original Unicode input visible while comparing output.
Choose the direction explicitly: Unicode → Bijoy or Bijoy → Unicode.
