They are a non-breaking space
(\240) and a capital A with circumflex accent
(\302), I believe.
This may help you disable them... here
The keystroke for capital A with circumflex
is Option+E, release, shift A.
If you can't disable them, you can maybe run this to remove them:
tr -d '\240\302' < yourfile
or this, to remove them and replace your existing file if it is successful
tr -d '\240\302' < yourfile > $$.tmp && mv $$.tmp yourfile
