Possibly a naive question, but here we go :)

Assuming a long list of character substitutions (e.g. "Ä" -> "A", etc):

http://dev.alt.textdrive.com/file/lu/LUStringBasicLatin.txt

What would be a reasonable implementation to actually perform the 
substitutions?

Right now, I invoke gsub() repetitively for all the substitution pairs:

function self:basicLatin( aString )
        if aString ~= nil then
                local aMap = self:basicLatinMap()

                for aKey, aValue in aMap:iterator() do
                        aString = aString:gsub( aKey, aValue )
                end
        end

        return aString
end

This works, but quite slowly :)

The strings themselves are UTF-8 encoded, but I'm rather at loss on how 
to define a pattern to break those into meaningful 'characters' and let 
gsub() work in term of the pattern instead of each key.

Ideas?

Cheers
