#1

local t1 = “John D. Doe.”

local t2 = string.gsub( s1, “.”, " " )

print ( t2 )   —> nothing 

but replace “.” with something else, like  “+”,  it works.

#2

sorry, typo error:

should read as :

local t1 = “John D. Doe.”

local t2 = string.gsub( t1, “.”, " " )     

print ( t2 )   —> nothing   

#3

OK, i figured it out.   

must use “%.” to find the “.”    :)
