Never push BS (backspace) character to `text` in the gpu_cache example (!14) · Merge requests · redox-os / rusttype

Backspace didn't work correctly because the example code pushes \u{8} at line 230 and then removes it at line 236.

This PR prevent appending BS character (\u{8}) to text, and enables Backspace key to work correctly.
