I'm not sure how this is supposed to work... See for example d/9677 -- your tool gives "eval(unescape(escape𒡦𫱲𚁩👣𛡷𪑤𭁨𧠽𜀻𪐭𛐻𮀮𨡥𩱩𫡐𨑴𪀨𮀮𩡩𫁬𚀩𚐩𠰨𨐽𭀭𪐩🠰𙠦𮀮𩑬𫁩𬁳𩐨𞐶𜀫𚁘🐨𪐪𞐶𜀭𪐪𪐩𚠪𛠵𚡓𚁡𚐩𛀶𜀫𪐬𚁳🐲𝐭𚁓𚁡𛐱𚐪𚁢🐨𜐭𚀨𦐽𪐭𝀸𜀩𛰴𞀰𚐪𚠲𚐪𚠮𝐩𚐪𚠴𚠲𝀩𚡃𚁡𚐪𨠬𬰬𣑡𭁨𛡡𭁡𫠨𦐯𦀩𛀰𛀷𚐻.replace(/u../g,'')))" which is 225B

This is on Firefox 64.0, 64-bit, on Ubuntu. This may require a browser that counts characters differently?
u/metamero

just paste the compressed code on new dweet, it works. to remix you have to delete disabled atribute of post button on inspector. this is a #bug on dwitter page's char counting, but server counts right (number of unicode glyphs <= 140) so posting astral unicode chars works fine. there is this discussion on github... but the status now is at least inconsistent.
u/f8f82804

could you point me to that github discussion?
u/f8f82804

ahhhh yeah i see what you mean about inconsistent -- the new dweet shows 225/140 but still allows it to be posted, while the remix button is disabled with the same code
u/f8f82804

personally, I thought that this was intentional, and that the char counting was counting 16-bit char codes, not unicode code points (e.g. the difference between charCodeAt and codePointAt)

this doesnt like code like thsi: x.fillText('⬛⬜' ( I get a short output with an unterminated string constant errro on the dweet, but it finishes comprssing with code like this x.fillText(['⬛','⬜'] Which takes me up to a 140B output, yet doesnt run, Aggh, Im so close...

Flip Tables

u/4ce

Unwork in https://beta.dwitter.net/d/26366 maybe because CSS in beta.dwitter.net make invisible elements, d/22514 have invisible too, maybe need "#bug" tag?
u/KilledByAPixel

interesting, not sure why it doesnt work there
u/4ce

Little note about #bug " not visible elements in beta.dwitter.net : d/26366 , d/22514 "... beta.dwitter.net render "canvas id=c" before all element what been added through ≈"t||document.write"* therefore "input type=radio" in d/22514 just out of frame but them can be visible if delete "canvas id=c" ; But in d/26366 need too change css class for visualizete border in table and need change something others for get result like in not beta version. TestLinks: https://beta.dwitter.net/d/26366 , https://dwitter.net/d/26366 ; https://beta.dwitter.net/d/22514 , https://dwitter.net/d/22514 ; // *"t||document.write" in d/22514 little other "for(i=2e3;!t&&i--;)document.write" but same logic...

i'm a newcomer, but codegolf community must decide whether they like to count code size in UTF-16 characters, UTF-16 code units or bytes (or bits, since b and B are different units)

#bug
u/f8f82804

I'm personally against exploiting a bug, so I prefer counting 16-bit chars.
u/metamero

u/f8f82804 unicode chars can be 16 or 32-bit (only). this bug is on front, not on server. or stated other way, this bug is on codegolf community policies.
u/metamero

speaking about bugs, this code actually counts UTF-8 chars (as they are represented in the page/editor). one can see this matter with the ௸ symbol (it's 2B long in UTF-16 but 3B in UTF-8). parameter 'utf-16' in TextEncoder is obsolete, see this note here https://developer.mozilla.org/en-US/docs/Web…
u/metamero

d/11906 is my method to count UTF-16 chars
u/metamero

*** this code actually counts bytes of the string encoded with UTF-8 (html context). d/11906 counts bytes of the string encoded with UTF-16 (javascript context). both count Unicode chars (or *code points*) right with Array.from(code).length. this is different from counting *code units* (16-bit unsigned elements).
