BUG=606705

Glyph 65535 means that the glyph is not printable.
Replacing it with 0 results in a striped glyph that's
rendered instead of non-printable glyphs.
Just remove old invalid code to fix this.
In my testing no Skia asserts were triggered.

Without this fix the title in tab of url :
https://www.google.ru/trends/yis/2016/RU?autoplay=1
will be incorrect rendered:
