Non UTF-8 characters make the qrcode invalid

[agijbels]

Can be reproduced using

https://codepen.io/davidshimjs/pen/NdBYrg

In the JS, line nr 12, change to following: qrcode.makeCode("íadsfasdsöadfas");

It doesn't draw anything.

I observed some strange behaviour regarding this.

ö works ö1 works ö12 does not work ö123 works ö1234 works ö12345 does not work ö123456 does not work

it does not matter if the chars after ö are 1 2 3 or a b c . Same behaviour for äÄ öÖ and üÜ.

This issue was fixed by pull request #273. Thanks to 19z.

Looks like this repo is no longer maintained, so you can find the fork here.

The minified version of that fork returns an error here:

Uncaught SyntaxError: Unexpected identifier (at qrcode.min.js:1:16790)

However downloading the non-minified version and minifying it myself works. So, looks like the minified version of the fork is corrupted.

(and I can't find a way to contact the fork's author @19z either, so I'm leaving this warning here...)
