Forums: Index > Help desk > Reserved characters

I can't find any documentation for what characters should be escaped in a wiki.

Here is what I have been able to infer:

' [ two or more times for wiki formatting
{ two or more times for wiki features
 : * # (in the first column) for indents/lists
= (in the first column?) for headings
- (in the first column?) four times for a horizontal rule
~ three or more times for a signature
# sometimes prefixes key words like REDIRECT
< (less-than) should be ampersand-l-t-semicolon

The current tips, imported from html, break the wiki rules in a few places, and have many other characters escaped.

When you edit some tips, you see a blizzard of *lt; *gt; *amp; *#35; (I've used * instead of ampersand here - that's less-than, greater-than, ampersand, hash).

The character escaping makes editing some tips pretty hard. Following the "be bold" policy, I have removed all escapes, other than less-than, from a couple of tips.

Now I'm getting nervous. What do you think?

Can you add anything to my list of reserved characters?

It would be nice to have a definitive list of reserved characters, and some Vim techniques for finding and handling problems.

The pipe character | seems special as well, it needed escaping in VimTip639 for example. Ipkiss 10:18, 21 July 2007 (UTC)
Thanks for joining in. Yes, I've learnt about pipe since writing the above. The problem is that the body of a tip is actually the 'text' parameter of Template:Tip. Therefore, the body must not break the rules for a template parameter. To insert a pipe you need to use the {{!}} template. I'm busy trying other things now, but I hope to get back to this point one day and find out whether there is any benefit from having the tip body as the 'text' parameter. --JohnBeckett 10:32, 21 July 2007 (UTC)
