You keep making it more and more difficult for the rest of us to
To start with, your use of "PUA" is not what is generally meant by
There is no such thing as "a" PUA; there is only one Private Use
Area, which consist of all the codepoints that will not be assigned
a specific use by the Unicode Consortium. You cannot say that the
range of codepoints U+E000..U+E0FF is a different PUA than
Secondly, you must be aware there is not, and will not be, a rule
about what characters in that area should look like. Yet you insist
on trying to convince everybody it's a good idea to remap, for
example "banana" to U+E100, even if the font calls it U+E000. You
keep on about what a good idea it would be to be able to rearrange
code points such that no matter how many fonts you have in use,
there is always a banana at U+E100. This is a restriction, an
unwelcome intrusion on the PUA!
You also can't seem to decide if this is just something you want to
do on your own computer, or if you also want to use this scheme for
information interchange with other users.
Now what you do in the privacy of your own home is none of our
concern, but when communicating with the outside world, there are
certain rules and guidelines you should abide by. And one of those
guidelines is a plaintext file should not have PUA characters in
them, unless its author also specifies it should be displayed using
a certain font. Now if the font it should use is known, the proper
codepoint to display this banana of yours is also known, because
this info is in the font. Ergo, no need to remap!
Since not all fonts have a banana, it really doesn't make much sense
to not specify a font. The computer wouldn't know what to do!
Lastly, I must say I think it's a pity that the suggestion I made
yesterday has been ignored so quietly. You know, in a HTML
environment, to retrieve names for characters from the font file
itself, to relieve the author from the task of having to enter
For an example, suppose you have a font named "Tengwar Quenya", with
a character named "hwesta" at U+E00B, you could use it in an XML
file by defining an entity, <!ENTITY hwesta "">. Now my
suggestion was the browser program which displays this file should
be able to look at the font information in the XML file, open the
font file and retrieve the names of all characters in it, so it can
show the "&hwesta;" character (and all other characters) without
needing a long list of ENTITY entries in the XML.
Anyone else think this would be a good idea?
