So far so good. There would be no reason for doing such a thing. If the author of a scholarly work used U+0364 (COMBINING LATIN SMALL LETTER E), this character should be displayed as either a letter "e" superscript to the base letter, or as an empty square (for fonts not caring about that character). > or, for that matter, the diaeresis as a combining > letter small e (however, you see the latter version > sometimes, very infrequently, in advertisement). This is the case I though we were discussing, and it is a very different case. Standing Keld's opinion and Marc's wholehearted support, it follows that those infrequent advertisements should be encoded using U+0364... But U+0364 (COMBINING LATIN SMALL LETTER E) belongs to a small collection of "Medieval superscript letter diactrics", which is supposed to "appear primarily in medieval Germanic manuscripts", or to reproduce "some usage as late as the 19th century in some languages". Using such a character to encode 21st century advertisements is doomed to cause problems: 1) The glyph for U+0364 is more likely found in the font collection of the Faculty of Germanic Studies that on the PC of people wishing to read the advertisement for "Ye Olde K�ster Pub". So, most people will be unable to view the advertisement correctly. 2) The designer of the advertisement will be unable to use his spell-checker and hyphenator on the advertisement's text. 3) User's will be unable to find the K�ster Pub by searching "K�ster" in a search engine. What will actually happen is that everybody will see an empty square, so they'll think that the web designer is an idiot, apart the professors at the Faculty of Germanic Studies, who'll think that the designer is an idiot because she doesn't know the difference between U+0308 and U+0364 in ancient German. The real error (IMHO) is the idea that font designers should stick to the *sample* glyphs printed on the Unicode book, because this would force graphic designer to change the *encoding* of their text in order to get the desired result. Another big error (IMHO, once again) is the idea that two different Unicode characters should look different. The difference must be preserved when it is useful -- e.g., U+0308 should not look like U+0364 in a font designed for publishing books on the history of German! What should really happen, IMHO, is that modern German should be encoded as modern German. A U+0308 (COMBINING DIAERESIS) should remain a U+0308, regardless that the corresponding glyph *looks* like U+0364 (COMBINING LATIN SMALL LETTER E) in one font, and it looks like U+0304 (COMBINING MACRON) in another font, and it looks like two five-pointed start side-by-side in a third font, and it looks like Mickey Mouse's ears in <Disney.ttf>... _ Marco
