and moving beyond the "nerd" stigma, so I'm not surprised there's chatter on the Unicode list.</span></p><span style="font-size: 16px; white-space: pre-wrap;"></span><div><br></div><p>I have been looking through</p><p><br></p><p>https://www.pbs.org/newshour/show/october-13-2022-pbs-newshour-full-episode<br></p><p><br></p><p>but I could not find anything about glasses emoji.</p><p><br></p><p>> <span style="font-size: 16px; white-space: pre-wrap; display: inline !important;">William, I'm curious: Why are you leading with a ZWNJ instead of placing it between the to-be-ligated characters?</span></p><span style="font-size: 16px; white-space: pre-wrap;"></span><p><br></p><p>The reason that I am leading with a ZERO WIDTH JOINER is so as to produce a combining version of eyeglasses without any need for an additional character for COMBINING EYEGLASSES to be encoded into Unicode.</p><p><br></p><p>As I understand it, and please correct me if I have got it wrong, up until now the encodings approved by Unicode Inc. to produce a display of an emoji character that is generated from a sequence of emoji characters in a ZWJ-separated sequence, has been to encode a complete sequence.</p><p><br></p><p>Upon checking in</p><p><br></p><p>https://www.unicode.org/charts/PDF/U1F780.pdf<br></p><p><br></p><p>I found that LARGE PINK SQUARE is not encoded.</p><p><br></p><p>I may have seen it proposed somewhere.</p><p><br></p><p>Pink is included as one of the fifteen colours encoded in my research project on localizable sentences.</p><p><br></p><p>http://www.users.globalnet.co.uk/~ngo/localizable_sentences_research.htm<br></p><p><br></p><p><span style="display: inline !important;">So in order to continue here I will switch from the pink that I mentioned previously for the eyeglasses to red.</span><br></p><p><br></p><p>However, in order to indicate pink rimmed eyeglasses a sequence including LARGE RED SQUARE and U+2B1C WHITE LARGE SQUARE could be used to mix the required colour.</p><p><br></p><p>https://www.unicode.org/charts/PDF/U2B00.pdf<br></p><p><br></p><p><span style="display: inline !important;">So, for example, to encode a woman wearing large round red rimmed eyeglasses and wearing a purple hat would be to have a complete sequence of</span><br></p><p><br></p><p>WOMAN ZWJ EYEGLASSES ZWJ LARGE RED SQUARE ZWJ LARGE CIRCLE ZWJ WOMANS HAT ZWJ LARGE PURPLE SQUARE</p><p><br></p><p>and then a font would need a glyph for that image to be encoded in the font so that the glyph could be substituted for the sequence in the display.</p><p><br></p><p>The U+25EF LARGE CIRCLE is in</p><p><br></p><p>https://www.unicode.org/charts/PDF/U25A0.pdf<br></p><p><br></p><p><span style="display: inline !important;">So, not very likely to be encoded as a recognized Unicode sequence for interchange.</span><br></p><p><br></p><p>However, if one encodes separately</p><p><br></p><p><span style="display: inline !important;">ZWJ EYEGLASSES ZWJ LARGE RED SQUARE ZWJ LARGE CIRCLE</span><br></p><p><span style="display: inline !important;"><br></span></p><p><span style="display: inline !important;"><span style="display: inline !important;">ZWJ WOMANS HAT ZWJ LARGE PURPLE SQUARE</span><br></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><br></span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;">then neither, either, or both can be used after WOMAN and a good display produced.</span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><br></span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;">Indeed it could be that one could use</span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><br></span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><span style="display: inline !important;">ZWJ EYE GLASSES LARGE RED SQUARE LARGE CIRCLE</span> </span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><br></span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><span style="display: inline !important;">ZWJ WOMANS HAT LARGE PURPLE SQUARE</span><br></span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><span style="display: inline !important;"><br></span></span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><span style="display: inline !important;">using the ZWJ only at the start of the sequence.</span></span></span></p><p><span style="display: inline !important;"><span style="display: inline !important;"><span style="display: inline !important;"><br></span></span></span></p><p>So if several types of glasses were encoded in this way, then each of them could optionally be used with various emoji, not just with WOMAN.</p><p><br></p><p>There is then the issue of what about emoji of groups of two or more people and one or more of them wears glasses.</p><p><br></p><p>I have thought of this and have concluded that a sequence such as</p><p><br></p><p>ZWJ EYEGLASSES LARGE RED SQUARE LARGE CIRCLE LEFTWARDS ARROW</p><p><br></p><p>could be used to place the eyeglasses on the person on the left of a two person group, and so on, incuding diagonal arrow characters if there are four people in the group.</p><p><br></p><p>https://www.unicode.org/charts/PDF/U2190.pdf<br></p><p><br></p><p>William Overington</p><p><br></p><p>Saturday 15 October 2022</p><p><br></p><p><br></p><p><br></p><blockquote
