I found a lot of answers to my questions in this forum but this time I have to create a new question.
I wanted to use the letter ø in my document, and because there was no easy solution for this, someone told me to use the command
\char28 to create this letter.
As I understand, this solution is specific to the font I am using because it is somehow printing the letter stored in the slot that is defined by the number.
My question is now how can I find out which number produces which letter in my PDF?
Thank you in advance.
