RE: removing diacritical marks from strings

[Jay Carlson <nop@...>]

This is all predicted on being in a single-byte locale of course.  "." only matches a byte, not a character.

When Modula-3 came out, we thought it was a little daring and progressive to define the language as ISO Latin-1 rather than ASCII....

Try something like this (untested):

local t={
	['A'] = "ÀÁÂÃÄÅ",
	['E'] = "èéêë",
	...
}

local T={}
for i=0,255 do
	local c=string.char(i)
	T[c]=c
end
for k,v in pairs(t) do
	for i=1,#v do
		T[v:sub(i,i)]=k
	end
end

now use string.gsub(source,"(.)",T)
