If you got the copyright symbol © to work for you with Alt+0169, I think that Alt+0176 should get you the symbol for degree as in 32°.
Please give it a try in the Premiere Elements opened Titler and let us know if that worked for you.
That worked at the second attempt (first try produced some sort of snowball).
1) How did you find that out?
2) I placed the cursor at the desired point within the text field & the degree symbol appeared elsewhere in the line.
Not a problen to cut & paste to where I wanted but I've seen this before with copyright & tilde symbols.
Great news that ° worked for you.
My secret...I found it online. I had never gone looking for it before.
Please let us know if it continues to work OK. I can use that Alt + 0176 for the degree symbol if I am typing in the forum as well as in the Premiere Elements Titler (Windows 7 and 10 64 bit)...it works for me with the numeric keypad and the Alt key of the computer main keyboard.
