This is Grade 1 Braille — every letter written out.
Published books, signage and anything an embosser produces are usually Grade 2, which contracts around 180 common letter groups and whole words, with rules about when each contraction may be used that depend on how a word is built and what it means. That is a linguistics problem rather than a lookup table, and it is not what this does.
So: fine for learning the cells, labelling something, or checking a transcription character by character. Not a substitute for a Braille transcriber if it is going to a reader.
The cells
Digits
Digits are the letters a–j behind a number sign ⠼, and one sign covers a whole run — 123 is ⠼⠁⠃⠉, not three signs. A letter a–j straight after a number is the same cell as a digit, so a letter sign ⠰ goes between them to keep “1a” from reading as “11”. Capitals take dot 6 in front: ⠠.
