Letter 'm' in font readability issues

[ronaldstoner]

The letter 'm' does not appear to be symmetrical on the Ledger Nano S display. This was confirmed by zooming in with a mobile camera and taking a picture of the pixels comprising the letter.

Issue: This causes a readability issue to some users where the letter may appear as an 'rn' instead of an 'm'. This may cause confidence issues during verification and open the user to potential address impersonations (although this risk is extremely low due to other security controls already in place).

Fix: Test a font with a mirrored symmetrical rendering of the letter 'm', (and verify other mirrored letters) to increase readability on the display.
