#messy #rainbow

u/DaSpider

Somehow the compressed tweet shows as longer than the uncompressed code, and oth exceed 140 characters?! 😕
u/f8f82804

There's a mismatch in the way that characters are counted -- this compressor uses 32-bit characters which are counted as 2 bytes in the front end, but are counted as 1 by the back end. I think there's an issue on the Dwitter GitHub where u/lionleaf has some comments about why.
