Hi Chris, Yes, apologies, I should have stated that I was referring to the non-Unicode STIX characters, so thanks for clarifying. Regards - Simon. -----Original Message----- Date: Fri, 20 Jan 2012 00:34:53 -0500 To: "jats-list@xxxxxxxxxxxxxxxxxxxxxx" <jats-list@xxxxxxxxxxxxxxxxxxxxxx> From: "Maloney, Christopher (NIH/NLM/NCBI) [C]" <maloneyc@xxxxxxxxxxxxxxxx> Subject: RE: Use of STIX font characters (Archiving v3) Message-ID: <5377500297A5C54EAB355784469119B12C314B76EB@xxxxxxxxxxxxxxxxx> > the use of entities defined by the STIX project ... but there is no > examp= le=20 > to illustrate the use of a STIX character I think you are asking primarily about the STIX-specific characters that they define in the PUA, right? STIX doesn't define any "entities" (as, for example, "ˆ"). After some Googling around a bit, I got the sense that the STIX group was involved in defining entity names earlier on in the project, and perhaps that's where the wording in the JATS documentation comes from. But anyway, I'll just assume you're talking about the STIX-specific PUA characters. I agree that one could interpret the JATS documentation as suggesting that it's okay to go ahead and use these. On the other hand, it states, "Use of private publisher entities and the Unicode=99 Private Use Area is discouraged ...", without reference to STIX, so it is a little bit ambiguous. For many of the STIX-specific PUA characters, it's possible to find standard Unicode characters to use instead (either a single one, or a combination using a diacritic), and that would be preferable. For example, STIX E21B is a right wavy arrow with slash, and if you follow their master configuration table (http://www.stixfonts.org/charactertable.html) to the detailed table (http://www.stixfonts.org/tables/E0_Non-Unicode_Symbols_Thru_E7_RU_V0.9.= html) you'll see it has an entity name "nrarrw". This is an entity defined in isoamsa.ent. From the W3C XML entities recommendation (http://www.w3.org/TR/2010/PR-xml-entity-names-20100211/isoamsa.html), you find that they suggest using the combination U+219D, U+0338 for this. But the example you mention, &xE0D1;, is a STIX-specific PUA character that doesn't have any entity name, and so it might be hard to look up something suitable in Unicode. Whether or not a particular document that uses this character can be rendered on any system depends entirely on the system. It's in the STIX fonts, so a site that delivers these documents as HTML could either suggest that their users install the STIX fonts on their systems, or else include it as an embedded font. As to the question of whether or not the JATS specification intends that these characters can/should be used directly in documents (without a <private= -char> element), I can't answer that. Cheers!

Each STIX character has a Private Use Area (P= UA) code point... for example that for "Chemistry: converging bond" is &E0D1;. So, is it correct to say that one can simply use the STIX code points in this way in an NLM file (i.e. there is no need to use <private-char> combined with glyph images)?
