Bash backspace character correct use

I did a pretty simple thing.

echo -e "123\b4" >> simple
cat simple
124

But when I open this file in Sublime text I get some characters called "BS" which probabvly stands for backspace, and when i open it with gedit I get a space instead and 4 after the space. which is the correct version of the file?

and when I open the file on the commandline with vim I get a 

^H

character instead.

Can someone please offer guidance?

\b simply takes cursor to left by single character. Its upto each editors interpretation to this symbol!

The correct version of the file is the one saved on the filesystem. Sublime text and gedit are reading the file and representing in different ways.
