[Unicode] Re: Fonts and font sizes used in the Unicode

I remember, the front page of the code charts by
Unicode has following note:

The shapes of the reference glyphs used in these code
charts are not prescriptive. Considerable variation is
to be expected in actual fonts. The particular fonts
used in these charts were provided to the Unicode
Consortium by a number of different font designers,
who own the rights to the fonts.

See http://www.unicode.org/charts/fonts.html for a list.


I have a question; if some people try to make a
translated version of Unicode, they should contact
all font contributors and ask for the license?
Unicode Consortium cannot give any sublicense?

If I understand correctly, ISO/IEC JTC1 hold the
copyright of the materials used in the published
documents of JTC1 standard, because they have to
permit the production of the translated version of
their standards, the reuse of the content of a spec
by another spec, etc.

Thus, I guess, it would not be so irrelevant to ask
the permission to JTC1, about the fonts used in
ISO/IEC 10646 - although it does not mean that
JTC1 would permit anything. If I'm misunderstanding,
please correct me.

> The editors of the Unicode charts will use any font resource that gets the job done (that is, results in a chart that correctly displays the characters in the standard). These fonts are often not production fonts, and may lack any of the many tables needed to actually display running text. They may also, as has been mentioned, be licensed solely for the purpose of publishing the standard. In some cases, they are custom built.

There are some examples where a character is very wide or tall where it had to be scaled down individually to fit the cell.
> The purpose of the code charts is *exclusively* that of helping users of the standard identify which character is encoded at what code position. They are not intended as a font resource or normative description of the glyphs. Any usage scenario that is outside the very narrow scope is unsupported and reverse engineering / extracting font resources is explicitly in violation of the terms of use.
