Variable name edit

Due to my own stupidity, I spent an inordinate amount of time chasing down an unresponsive trigger based on a change in variable A. Eventually I found that I also had a variable A_ (where _ is a space). This occured because that variable disappeared during an import from one machine to another. It appears to be typical. Fix that if you can, but if you would strip off trailing spaces from variable names before deciding if the name is unique, it would be great. I see no advantage to two vars named A and A , where the only difference is a trailing space.

The extra space seems to be a Samsung tablet thing. It does not occur on my Motorol phone. When I name a new variable the device adds a space to the name, just as it does when I type here. It may be because I selected a word from the top row. In any case,,can you help :)
