Square bracket incompatibility in TiddlyWiki code

Hi Will,

I think TiddlyWiki is well written that's why the escape you used won't work since it is being used in a URL :-)

However you made the penny drop for me since it made me realize that what is needed is URL encoding. I was thinking it was an equation problem when in fact it is a URL problem

i.e. [=%5B and ]=%5D

Therefore what is needed is:

[img[http://latex.codecogs.com/gif.latex?\sqrt%5B3%5D{x+y}]]

This is a good fix as it is standard URL encoding and will work in any equation in any browser. It appears to render right when pasted into Equation Editor so...

See example at:http://twmath.tiddlyspot.com/#SquareBracketBug

What do you think?
