You can now enter more than 140 characters while writing a dweet! (But you can't post anything longer than 140 characters)

u/iverjo

Sweet :) I remember removing maxlength=140 in my dev console when creating dweets at arkt.is/t/ ^^
u/PhiLho

Yes, that's what I did here as well... :-D Ah, except I get an alert dialog on each character beyond 140! Not very practical to type. The red counter should be enough...
u/PhiLho

And apparently we can now safely replace semi-colon with newline, even on Windows! (they counted as two chars, previously...)
u/iverjo

Yes, that alert should be removed. Luckily, one can suppress it in FireFox by checking the checkbox inside the alert
u/lionleaf

Ooops, I never got the alert for some reason. And I didn't see this before now. Should be fixed now.

It turns out that this looks different with the Windows 10 Anniversary update

Just barely hit the limit.

declare w in the first text to save 2 bytes ;)
