So how do we tell writers of rendering engines that it is OK to
have U+0078 with Lao vowel marks? (I'm not entirely convinced this is
the reason for having 'x' on the Lao keyboard.) I'm still not seeing
much sign that they believe that all marks may be allowed on U+00A0
NO-BREAK SPACE or on U+025CC DOTTED CIRCLE.
