string.gsub and "." don't work?

[Genete]

A call to this function

Code: Select all

string.gsub("hello.world.bye",  "." , "-")

returns

Code: Select all

--------------- 15

It would work as this:

Code: Select all

string.gsub("hello#world#bye",  "#" , "-")

returns

Code: Select all

hello-world-bye 3

Why the dot "." doesn't work in the string.gsub function?

The dot "." is a magic pattern parameter that represents any character
Using "%." instead it works!!


Thanks anyway!
