:It looks like the wikifunctions are using a different character for "D" than [https://scream-cipher.netlify.app/ the github project] linked in the explanation.

Is there a logic behind the choices of the letter? I guess A̧ is for C because of the French ç and Å is pronounced like O in some Nordic languages. Also, is it A̱, A̲ or A̲ ? (or something else). [[Special:Contributions/172.71.126.50|172.71.126.50]] 18:10, 21 February 2025 (UTC)

:Look to the likes of the [[1190: Time]] comic, where several different fanbase compilations may have been given. I would anticipate that you could do a decent job of editing "This thing here does..." into "Ways of experiencing it include this [existing one] and that [yours] [with room to add more, if they add up]. Or just mention your link here, let others decide if your claims of (better?) functionality stand up enough to prompt it to be put up alongside/ahead/instead of the other. I am at least intrigued as to how you did it differently.

I know you can decode a substitution cipher by counting letters and replacing common ones like 'E' and then filling in the rest by inspection, but what kinds of automated approaches are there? [[Special:Contributions/162.158.159.105|162.158.159.105]] 20:14, 21 February 2025 (UTC)

'''HEADS UP:''' I just changed A̲ (0332 COMBINING LOW LINE) to A̱ (0331 COMBINING MACRON BELOW) as encoding for "D" in the table and the transcript. Rationale: "T" is written with macron, so it's only logical to encode "D" likewise. A "low line" is longer than a macron, and looking at Randall's comic, the line below the "D" is definitely not longer than the one above "T". It would also make no sense to encode "T" with a "combining low line" as well when a single, uncombined character exists. [[Special:Contributions/172.70.114.123|172.70.114.123]] 20:29, 21 February 2025 (UTC)
: These options should all be including as different writing styles! I think the longer line makes it clearer that A̲ represents D because the ink comes nearer to forming into a closed curve. [[Special:Contributions/172.68.54.68|172.68.54.68]] 15:55, 22 February 2025 (UTC)

I expect to win a Turing Award for my proof this cypher is computationally equivalent to https://en.wikipedia.org/wiki/Whitespace_(programming_language) [[Special:Contributions/172.71.158.19|172.71.158.19]] 02:57, 22 February 2025 (UTC)

The page technically uses the incorrect characters for (at least) E, M, N, O, R, S, and T based on the title text shown on xkcd.com. The original title text uses two separate characters (ex. A + 0301 COMBINING ACUTE ACCENT for E), whereas the table uses the combined character (ex. 00C1 LATIN CAPITAL LETTER A WITH ACUTE for E). Alternatively, my browser is just doing something weird. Not necessarily worth updating, but something I noticed when implementing the cipher. [[User:Abus|Abus]] ([[User talk:Abus|talk]]) 06:22, 22 February 2025 (UTC)
: I think it's the browser. Firefox->Page Source gives me A+COMBINING WHATEVER, but <code>w3m -dump_source https://xkcd.com/3054/ | zcat | grep 'img.*title='</code> returns single characters. The title text here on explainxkcd was copied by ''TheusafBOT''. I trust ''TheusafBOT'' and ''w3m'' to be so basic and simple that they wouldn't try to do something 'clever' with the characters, whereas I tend to suspect the multi-MB-monster Firefox messed things up. I'm just guessing, though... could maybe someone test with yet another browser - e.g. Edge or Opera? [[Special:Contributions/162.158.159.107|162.158.159.107]] 11:52, 22 February 2025 (UTC)
:: Argh, no, turns out ''w3m'', and also ''wget'' all return A+COMBINING THINGY, but they got merged into the single chars by my ''xterm'' when I copied them to some 'identify unicode' web page. Looking at the raw file dumped by ''wget'' I see A+COMBINING XX - I think... So I think you are right with your observation! Randall uses A+COMBINING XX for the title text on XKCD (though I really doubt that was intentional), then ''TheusafBOT'' merged the characters when it copied the text to create this page. That said, I still think using the merged chars is cleaner. [[Special:Contributions/162.158.159.107|162.158.159.107]] 12:20, 22 February 2025 (UTC)
::: It may be worth noting the difference somewhere, even though the merged chars are cleaner. Someone copying the characters from this page to encipher text would technically be in violation of the "spec" since Randall used the two character version in the title text. If someone wished to decipher the title text from the original XKCD, this characters on this page would fail. [[User:Abus|Abus]] ([[User talk:Abus|talk]]) 18:56, 22 February 2025 (UTC)
