Printing Alt Codes

Is there something special you have to do to have ALT codes print? I placed some boxes ALT 0141 into some text and they don’t print either to paper or PDF.

Thank You

I noticed the same thing with ALT+0141 that you are experiencing. You may want to try ALT+11036. Works well for me and prints nicely. You can also use the Character Map for a slightly different look using SEGOE UI EMOJI. I did enlarge the font size on the squares for a better look. Not sure how this image thing works. Suspect I will find out.

No issue for my side…
Do your font support the unicode?

Do they show up correctly in your SW Drawing?

Yep.

PDF and any other print

That works for me too. Weird.
