Alot of letters and symbols change the game font to a different one

Certain special characters are meant to change the font (see: MCPE-139157) however alot of them probably should not because they are very common on certain languages.

Steps to reproduce:

1. Write something somewhere
2. Use these letters

Observed results:

The font is changed when you do it.

Expected results:

The mojangles font should probably be kept.

Notes: This does not happens on the new create world screen.
