    OK, it's safe, but it is a misuse of Unicode. As space plus combining
    character is a unit in Unicode, it should be treated as a unit by higher
    level protocols. If higher level protocols are allowed to do arbitrary
    things within Unicode units, there is no end to the possible confusion.
    See for example, from Unicode 4.0 chapter 3:

    C7 A process shall interpret a coded character representation according
    to the character
    semantics established by this standard, if that process does interpret
    that coded character
