Code charts and code points (was: Re: fonts for U7.0 scripts)

Unlike the public, the code chart editors for Unicode have tools that can correctly handle not only ASCII-hacked fonts as well as PUA-assigned fonts, but also fonts that use the wrong Unicode encoding (because they were designed for an earlier draft with different code point assignments). These tools ignore all shaping tables, so the lack of such tables isn't an issue. The documents created by the code charts editors are no editable in the normal sense, so they can be published without causing problems, like establishing a de-facto encoding. They don't contain running text in these fonts, so there isn't an issue with search - the searchable contents are all character names, annotations etc in Latin letters and digits. Releasing such fonts to the public would establish a de-facto non-sanctioned encoding, because people could create (and interchange) running text using them. Hello Asmus, The code charts are published as PDFs. In general, text in PDFs can be copypasted elsewhere. Is there something in place that makes sure that wrong Unicode encodings for glyphs published in code charts don't leak elsewhere?

Hi Martin. If you haven't noticed it before, opening Unicode charts in PDF readers has something like SECURED on the top i.o.w. the charts are sorta DRM-protected. So you can't copy-paste the characters. Heck you can't even copy-paste the character *names*! -- Shriramana Sharma ஶ்ரீரமணஶர்மா श्रीरमणशर्मा ___ Unicode mailing list Unicode@unicode.org http://unicode.org/mailman/listinfo/unicode

Like Jukka, I tried randomly copying a number of PDF code charts (from http://www.unicode.org/charts/) and I couldn't find any which were not using the correct Unicode code points (maybe there are some, but I gave up before I found them).

Looks like I spoke too soon -- I seem to distinctly remember this behaviour from earlier versions (or am I misremembering?!!!) but Unicode 7.0 charts don't seem to be this way... And SMP glyphs seem to be mapped to PUA chars. Not really ideal... BTW for older versions, individual blockwise charts don't seem to be available. I would presume the total size of individual blockwise charts isn't too much higher than the single http://www.unicode.org/Public/6.2.0/charts/ and Unicode versions aren't that too many anyway -- can we have individual block charts in archival rather than having to download 92 MB please?
