This is a function that takes two variables; the first one it calls
'str', the second one 'filename'. Example:
function f(a, b)
return a/b
end
function(8,2) --> 4, not 0.25
I do not know what sort of str and filename are being passed to
document.MyCharacterMess. (To all the action functions in
utilities.sequencers.appendaction, in fact).

file.nameonly strips path and extenstion, e.g.
file.nameonly('a/b/cod.doc') returns 'cod'.
You can see the file.* functions in l-file.lua.
string.totable splits a string, and returns the pieces as an array. In
this case, the string is split at the periods.
table.concat combines a table into a string, optionally putting a
string (" + ", in this case) where the pieces join.
so the `str = ...` line turns
"Hello. I am Sam. You are also Sam."
into
"Hello + I am Sam + You are also Sam"
or "hello.txt" into "hello + txt"

No idea.
Cheers, and good luck,
