Possible issue with ordinary spaces

There are (at least) two possibilities for representing ordinary spaces in a document that is in braille:
1. The ordinary space character, U+0020
2. The braille space character U+2800

The braille space, according the Unicode spec, does not have word breaking properties. It is defined as a symbol other.
The ordinary space is defined as a space separator, but may not be the correct width for a braille character.

Noting this in case it becomes important later.

Reading systems may be able to add word breaking possibilities to the braille space by adding one of the "thin" or "zero width" spaces available in Unicode.
