Can anyone tell me how to compress unicode emoji chars please?
u/cantelope

most of the compression techniques involve converting common (codes 0 - 255) ASCII to unicode, so you have a problem with embedding higher codes or emojis that use multiple higher codes. Here's one approach: https://dwitter.net/d/36129
u/NiVZ

Thanks. I think I used the same approach you did. I did try having a look at storing the emoji values as hex (with and without the repeating 0x1F) but adding the String.fromCodePoint() added more characters than it saved.
u/cantelope

i mean, the main thing is eval
u/tomxor

I've often place them in separate "uncompressed" variable e.g. s='🌞🔴🌍🪐';eval(unesc... then use s inside the compressed code.
u/NiVZ

u/tomxor Thank you that worked! I now have 8 planets :) https://www.dwitter.net/d/36151
