I've seen Japanese people write many letters/numbers "strangely". The most common one is D which is written with a stroke like this Đ
Why is that? Are there any other letters that are written differently from how it's done in Western countries?
Edit:
IIRC the number 4 is also written with a longer vertical stroke because I remember seeing Japanese people elongated foreign people's number 4 to make it clearer. I suppose because they think it's similar to Katakana ム?
Note that I do know that Japanese people don't write 7
with the horizontal stroke like the above font but with a hook above, because when I first learnt the language my teacher told me that they don't understand what that is. I did hear Japanese people asking what that 7 symbol is, or confirm if it's the number 7 when they're familiar with foreign handwriting.
And there are non-programming versions without the stroke on 0 as well:
