Welsh Braille is the braille alphabet of the Welsh language. Except for ⠡ch and ⠹th, print digraphs in the Welsh alphabet are digraphs in braille as well:
⠙⠙dd, ⠋⠋ff, ⠝⠛ng, ⠇⠇ll, ⠏⠓ph, ⠗⠓rh.
Accents are rendered with circumflex ⠈, diaeresis ⠘, grave ⠆, acute ⠒.
Welsh Braille also has a number of contractions.[1] Punctuation is as in English Braille.
