Fix #135097: BLF Control Characters in When Wrapping

With 4da5377e17 control characters are shown as space characters. But
word wrapping code will use the codepoint from the glyph if available,
which means a soft wrap on space instead of a hard wrap on line feed.
Just oversight, no need to use the glyph for that. In fact we always
want to deal with the character, not the visual representation of it.
