Re: gsub without patterns

["John Batty" <john@...>]

I don't think that there is (and agree it would be useful).

I ended up doing the following in my code:
        --------------------------------------------------------------------
--
        -- Convert all non-alphanumerics to have a "%" escape character, to
        -- ensure that Lua doesn't interpret them as special characters.
        -- However, this means that any checks in the following code for
        -- non-alphanumerics must check for %[char].
        --------------------------------------------------------------------
--
        interest = Text:makeSafe(interest)
        gsub(document, interest, ...)
----------------------------------------------------------------------------
--
function Text:makeSafe(text)
    return gsub(text,
                "([^%w%s])",
                function(nonAlphaNum)
                    return("%"..nonAlphaNum)
                end)
end
