Braille
Braille is typically 2x3 cells of embossed dots. In puzzles where the touch aspect is not required for accessibility it can be presented in theme as 2x3 cells of circle-like things. Puzzles typically only use "Grade 1" English Braille which is a simple transformation of letters.
If you have a Braille letter not shown here it might be "Grade 2" Braille which allows for complicated contractions, but in the world of puzzles more than likely you've made an error.

In the table above W is shown out of order to make it clear how Braille can be learned: the top four dots count the column number and the bottom two dots count the row number. W was not included initially in Braille because the alphabet used as the basis for the Braille alphabet (the French alphabet) does not have a W.
