Cases where ` 's are used for quoting are a big example of this. Typing `example` turns into èxample` on my keyboard because the backtick key is a modifier for the next press. To type `example`, I need to type:

* On Linux: ``example`

* On Windows: ``<left>example

Some editors even turn the latter into ```` when I double press the backtick as no symbol renders prior to that.
