So far I cannot reproduce this problem. How easily can you reproduce this? Is this a display only problem, or is the actual content of the file being modified?
How exactly are you selecting the "h"? With the keyboard? With the mouse?
It's only a display issue, but it happens whether I select with mouse or keyboard. It doesn't always happen - it seems be dependent on what else in the file - but with a file containing only "\\hi" or "\\a\\b\\c\\" for example, I can reproduce it every time.
and paste the details (from the clipboard) into your reply. This will give us the basic information about your setup. I am mainly interested in the IDE font and VA version.
