Special character

Hi all,

I have a question about inserting a special character:

situation: the lines I am building are indicated not with numbers but with letters.

Problem: despite having created codes on the "special characters" table with the letters I am interested in, I only see numbers. The route indication works great.

I am therefore still trying to understand how it can display, in fact, the single letter and where and how to insert the special code. In the editor? In the Content? I do not know.

I have read many times in the lexicon but cannot understand.

I am referring to the external matrix.

Thank you

Thank you for your answers

The image of the content you posted is just what I'm trying to do and the photo of the bus exactly reflects one of the letters that I have to insert. Now I'm not in front of the pc, but yesterday I did exactly this but it doesn't work. (I only use A-Z characters). I did not understand what they are for (#) and (R1-R2) ... Unfortunately, even translating lexicon certain sentences are difficult to compose.

Since I am creating a line that follows the path "A > B > A" and that has to change matrix once it reaches "B" (always keeping the letter of the line the same) maybe I did something wrong in inserting the codes. I edited your images to show you how I did it.

mmmmmh... It's a nice puzzle.
I don't know if I will understand it but I'll try now.

Thanks everyone, I solved it.

I don't know if that's right but that's enough for me. To get just the letter I did this: A(##) B(##) C(##) etc. I hope it might be useful to someone.

Thanks again for the support
