Unicode characters?

Should we write down the characters on the coins even if the alphabet is a not so well-known alphabet?
I think yes, I think we are already using a variety of different Unicode characters in Numista, even some that do make some problems with some devices because of low font support

I wanted to add some information to this coin
https://en.numista.com/catalogue/pieces8487.html

Reverse
Value above coffee branches and initials of the "Banco Central de Costa Rica"
Value in Braille (incorrectly spaced, could as well read ⠑⠓⠃ "582" instead of ⠁⠚⠚ "100")

Lettering:
100 COLONES
⠁⠚⠚ [addition]
B. C. C. R.

I think if the coin sheet already mentions the Braille characters, why act like in pre-Unicode times and not include them because some users might not have the optimal typeface installed?
