Alphabet
Stray’s alphabet is what I’d like to call a “Latin substitution.” This means that each letter in Stray’s alphabet can be translated directly to a Latin alphabet equivalent.
By scouring through a lot of in-game text, I have recorded most of the letters used in Stray, including some interesting variants (If you see multiple symbols above a letter, it means that letter can be represented by any of those symbols).
A quick side-note is that not all in-game text is actually translatable. Most signs are, but filler pieces of paper usually amount to total gibberish.
