If I may make a suggestion, you could just support one escape character -> \
That way, balanced or unbalanced, they just have to know one convention. If I
understood your examples correctly, i.e. these are the strings one would write
within url(), this is how they could do it:
special\(operation\)
special\(operation\(whatever\)\)
special\(operation{argument,argument{whatever}}\)
special\(operation{argument{whatever}}\)
special\(operation\(\)
special\(operation\(whatever\)
special\(operation{argument,argument{whatever}\)
special\(operation{"argument{whatever"}\)
And if they ever need a literal \ in their URL, they would have to write \\
In my examples above, I have escaped only ( and ) because they interefere
with url(). If the any other character interferes with your code, they could
escape it as I have shown.
