QR codes not shown in a usable fashion

[Donner-Party]

When using Teraterm to set up PiVPN, it does not display QR codes properly, no matter what font I have tried.

It does display properly in Windows 11 ssh client.

Can this be fixed or is there a specific font I should be using?

Hi

same issue?

Check the character encoding.

$ qrencode -t ansiutf8 https://teratermproject.github.io/

For correct display, please set character encoding to UTF-8. see setup - additional settings - coding tab and set UTF-8.

from man page

       -t    {PNG,PNG32,EPS,SVG,XPM,ANSI,ANSI256,ASCII,ASCIIi,UTF8,UTF8i,ANSI‐
       UTF8,ANSIUTF8i,ANSI256UTF8}

ASCII can usually be displayed correctly. (But it is difficult to read with a qr code reader.)

With the -t option, it still does not display correctly in Teraterm. I should have mentioned it does display correctly if I use Windows command line SSH.

However, I did find this at the pivpn website and it works:

Teraterm is set for UTF-8:

Please use Tera Term 5.2.

Set as follows.

When Ambiguous Characters width=2cell or Tera Term 4.x

Thanks! That helped, it is working now.

I also had to change the font to Consolas. I had been using Lucida Sans Typewriter.
