FAQ (http://unicode.org/faq/vs.html) states:
For historic scripts, the variation sequence provides a useful tool,
because it can show mistaken or nonce glyphs and relate them to the
base character. It can also be used to reflect the views of
scholars, who may see the relation between the glyphs and base
characters differently. Also, new variation sequences can be added
for new variant appearances (and their relation to the base
characters) as more evidence is discovered.
It states also:
What variation sequences are valid?
Only those listed in StandardizedVariants.txt...
However the file in question contains only sections for mathematics and
some rather exotic scripts.
To the best of my knowledge, the only attempt to introduce additional
variation sequences was the strongly criticised Karl Pentzlin's proposal
What has happen to it? I don't remember any information about it on the
However my primary question is:
Are variation sequences *really* recommended for historical scripts?
I ask the question because there are now several historical corpora of
Polish under development, which use at present a kind of fall-back or
some other ad hoc solutions for "nonce glyphs", as they are called in
