{,

Answer 1

I wanted to escape a quotation mark ("). Doubling it does not escape this,

I was able to force the hex-code by using {%|%22}.

On http://www.jrsoftware.org/ishelp/index.php?topic=consts this escaping is show as {%NAME|DefaultValue}. Leaving NAME empty makes it use the hex code.

Answer 2

You can escape the { by doubling it. There is no need to escape the } as it is only used if inside a constant.

From the help file:

A "{" character is treated as the start of the constant. If you want to use that actual character in a place where constants are supported, you must use two consecutive "{" characters. (You do not need to double "}" characters.)
