Configuration data escaping rules:

1. You can escape the format character (@) by preceding it with a backslash.

2. Backslashes not directly preceding a format character are not modified.

3. The number of backslashes preceding a @ in the output is equal to the number of backslashes in the input divided by two, rounding down.

   For example, given the string "\@" (one backslash), the output will contain no backslashes. Both "\\@" and "\\\@" (two and three backslashes) will produce one backslash in the output "\@".

Examples:

"\@" -> "@"

"\\@" -> "\@"

"\\ @" -> "\\ @"
