Tilde "~"#
Advantages:- Used on:
- JSPWiki
- Has semantic connotation wit "not", which might suggest the meaning when seen
- Pretty rare in normal text (but not unused)
- Not available on many Keyboards
- Hard to type under Microsoft Windows (Could you be more precise? I have no trouble typing it using MS Windows with a US or German keyboard)
- Traditionally used in text as an alternative to hyphen (eg. in number ranges) or meaning "roughly".
- The exact way of escaping is not obvous (eg. compare ~ }}} vs ~ }~ }~ })
- Used in programming languages for operators -- pasted code would need escaping, or could change its meaning.
- Conflicts:
Backslash "\"#
Advantages:- Extremely widespread for escaping in:
- Programming languages
- File names
- Regular expressions and search queries
- Traditional, obvious way of use (always escapes a single character)
- Never used in normal text
- Used in Microsoft Windows for paths
- Commonly used for forced line break (usually doubled)
- Used in programming languages for escaping -- pasted code would need double escaping, or could look bad.
- A bit confusing considering the double backslash proposed in Creole 0.4.
Caret "^"#
Advantages:- Never used in normal text
- Rarely used even in programming languages
- Sometimes used to mean "not"
- Not on all Keyboards
- No precedent (?)
- Conflicts with superscript markup on all wikis that have it
Percent "%"#
Advantages:- Commonly used for an alternate escape character, when backslash is not available
- for printf parameters
- for time and date formatting
- for colored text
- Established way of using (escapes whole chunks)
- Sometimes used in normal text to denote, uh, percents
- Used in programming languages for operators, escaping and variable marks -- code needs escaping or it will change meaning
- Conflicts:
