This might be a problem arising because of Han unification.

In Japanese, the character is commonly written with a vertical final stroke (at least in print), whereas in Chinese it's a diagonally down and to the right. However, they are encoded as the same in Unicode. What gets displayed depends on the font choice, possibly aided by somewhat hacky language hints.

This particular character is the second example in the list of "Examples of language-dependent glyphs" in the Wikipedia article [1].

FWIW, the version where the lower part is like マ is also used in Japanese. Different calligraphic styles can have big visual differences.

Much like how the lowercase a or g can have multiple appearances in the latin alphabet.

Speaking of this, my computer just switched from displaying Chinese by default to displaying Japanese. I was able to configure Firefox back to Chinese, but couldn't figure out how to set Windows 10 back. It only really affects me if I happen to be typing Chinese in Notepad, but still, it's annoying. Do you know how?

Thank you. This seems like a very probable explanation.

Jisho does not have the last stroke wrong, that is how you write the kanji. The way it is represented in computer fonts is different than how it is hand written. The jisho instructions show how to hand write it.

The confusion probably stems from the way it is written in the calligraphic representation of 令和 presented by the government, which does do the same vertical stroke as in print.

In normal handwriting マ is totally fine and common.

Yep, exactly! Certainly no expert on Japanese, just the only place I saw it written with the マ shape was my android device and jisho, so I assumed it was an error. Learned a new kanji today anyway!

Not wrong. Just a difference in how fonts display them. Like how ‘a’ sometimes has a little hook above it and sometimes doesn’t.

This is basically just a font difference. The angular version (in the text of your link) is the more typewritten style, while the version in the stroke order graph is the more handwritten style.

It's roughly analogous to the way "g" would usually descend on the right when written by hand, but descends on the left in most typefaces.

They are different variations of the same character. This is not very common but does occur. So it is a font issue.
