Howdy there!
I was adding some alt text to my shop, and stumbled upon the issue of "alt text too long" even if the character counter hasn't reached the limit -- it has been mentioned a few times here.
Just wanted to give everyone a heads-up that I found the culprit.
If you're using the character " in your description, it gets translated as " in the text.
So what happens is: the shop UI count your " as 1 (one) character, but when submitted it is turned into " by the server, now counting as 6 (six) characters... And this ladies and gentlemen is how you bust the character limit
Note that the above is probably true of other special characters.
Cheers!
