One problem is that there seems to be no way in plaintext unicode to specify
who is in charge of a particular interpretation of the PUA.
As I understand the position of the designers of Unicode they definitely
don't want to be in charge of this and want to let the users of the PUA
fight it out among themselves.
Nevertheless I think if Unicode don't want to decide how the PUA is to be
interpreted it should be at the very least provide a mechanism by which an
user of the PUA can specify which specification he prefers.
I plan to propose such a mechanism:
I want to propose a char with the following properties:
Scalar Value: U+E0002
This starts a PUA interpretation selector tag.
The content of the tag is a Font family name.
For all PUA chars between this tag and the corresponding Cancel tag the
copyright holder of the font is the sole authority about how the PUA should
