ASCII-friendly alternatives for invisible fingerprinting: - replace quotation marks with two apostrophes - replace “I” with “l” - replace parentheses with sl

ASCII-friendly alternatives for invisible fingerprinting:
- replace quotation marks with two apostrophes
- replace “I” with “l”
- replace parentheses with slashes or square brackets
- replace commas with semicolons
Each of these substitutions can communicate a single bit while being ASCII-safe and likely won’t change word wrapping opposed to synonyms.
- userbinator 9y agoAll of those except the last one are pretty obvious, especially if you're mixing them to "communicate a single bit". Speaking of quotation marks, the non-ASCII quotes in your second item and apostrophe in the last sentence stand out too.
- Too 9y agoThey are obvious if you have two copies and are actively looking for differences, otherwise not. If someone sent me a document with square brackets somewhere i wouldn't question their use of square brackets over parenthesis, unless they don't match.
- forapurpose 9y agoThere are many more options: Insert one of the many non-printing ASCII codes. Add an extra space, especially before a newline. Add or remove an extra newline at the bottom. Change punctuation where the choice is believable either way: Single quotes for double, commas for semicolons, periods for colons.
