Well, there are several ways to handle this.
The easiest would be to replace all '　' with ' ' before save the  
file or do something with the file.

If you want to see these double byte space you can add this in a  
language grammar under 'patterns':

{	match = '[^　]*(　)[^　]*';
	captures = { 1 = { name = 'meta.character.DBSpace'; }; };
},


and finally you can add an element within TM's preferences > Fonts &  
Colors called 'DBSpace' with the scope selector  
'meta.character.DBSpace' and set the background color (BG) to what  
ever you like.

The next idea would be to create a snippet with a single ASCII SPACE  
and bind it to a key equivalent SPACE.
