Hello,
I had written:
- In your HTML source, use only characters from the WGL4,
cf. <http://www.microsoft.com/OpenType/OTSpec/WGL4.htm>;
Peter Kirk has written:
Well, of course if you are using languages which use only characters from WGL4, you will use only these characters.
You can well write in an European language, and still use non-WGL4 characters, e. g. - U+03D0 through U+03D6, U+03F0, U+03F1, which one might wish to use for Greek (the reference glyphs of U+03D0 and U+03F0 were the way I have learned to write Theta and Kappa, respectively, in school), - the whole Greek Extended block, which is still used by a school of contemporary Greek typography (though no more in the official orthography), - U+2000 through U+200B: you have to use <kbd>  ></kbd>, and some such, to generate empty space, - U+2010 -- believe it or not: WGL4 does not comprise the hyphen, - some more General Punctuation, such as U+2012 (Figure Dash), U+2023 (Triangular Bullet), U+2027 (Hyphenation Point, used in dictionaries and glossaries, like Elaine's project), U+2032 (Prime), U+2052 (Commercial Minus Sign), - U+2070 through U+208E (Superscripts and Subscripts), except U+207F which is in WGL4 -- you will have to use HTML tags instead, which is more versatile, anyway, - a major part of the vulgar fractions U+2153 through U+215F (1/3 is not in WGL4, but 3/8 is), and all Roman Numbers U+2160 through U+2183 More examples are left as an exercise to the gentle reader: just compare <http://www.microsoft.com/OpenType/OTSpec/WGL4E.HTM> to the pertinent ranges in THE BOOK.
When I wrote the advice quoted supra, I was mainly thinking of some Punctuation and Symbols I'd like to use, which are not in WGL4.
Best wishes, Otto Stolz
