It's a common spelling in fantasy video games and books, but it feels kind of performative.

These same games will have voice actors pronounce "ye" as it's written, unaware that the y is a typographic substitute for Þ. "ye olde" is pronounced "the old". But likewise, there's some VAs that clearly only ever read a word, like in the newer God of War games where a character mangles "prescient".

Same had to actually look it up and at least Merriam-Webster lists the word as “chiefly British spellings of JAIL, JAILER”. Which at least hints that the dictionary writers thought it is less common out side of Britain.

It's the traditional spelling. You'll see it in the British Isles, and on some old buildings here in Canada.

Obviously, you haven't visited any colonial American sites. It used to be the normal spelling.
