Why does script for offline QR Code doesn't work for emoji symbols?

Publish date: 2024-06-26

My requirement is to generate QR code for below 2 texts in javascript/jQuery

Condition is that I can't use any URL feed to generate QR code online like below Google QR example
https://chart.googleapis.com/chart?cht=qr&chs=200x200&chl=ThisIsSomeText
If I use above, QR code for both texts are generated successfully(checked after scanning)

I only have to use any QR code plugin within my code to generate QR code offline(no network connectivity restriction)
So, I tried below jQuery plugins that would work offline

Plugin 1: https://www.studytonight.com/post/javascript-qr-code-generator
Plugin 2(qrenc3.html): https://code.google.com/archive/p/jsqrencode/downloads

If I use any of above 2 plugins, the QR code is properly generated for Text 1 only, not Text 2.
If text has emojis, it creates improper QR code. Check below generated QR codes.

For Text 1: (Plain text)below is code generated(proper text comes after scanning)
enter image description here

For Text 2: (Emojis)below is code generated(Unknown encoding or not scannable)
enter image description here

I need help if anyone can solve above or share any jQuery plugin (offline) that would generate QR code for emojis.

[I have not added any code as plugins already have demo in them. Hope that's fine]
Thanx in advance for help.
