Younger characters such as 😺❤🤓 are not categorized correctly, etc. ...). Luckily, there is already some logic to fetch the latest data from <a href="http://www.unicode.org/" class="OWAAutoLink" id="LPlnk135036" previewremoved="true">www.unicode.org</a>. I'm currently reworking this logic because it's not completely automated yet and has some slips, but so long, I have one general question for you:</div><div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class=""></div><div style="margin-top: 0px; margin-bottom: 0px;" class="">At the moment, we have 30 class variables each for one Unicode category number. These class vars map in alphabetical order to the integers from 0 to: 29. Is this tedious structure really necessary? For different purposes, I would like to get the category name of a specific code point from a client. The current design makes this impossible without writing additional mappings.</div><div style="margin-top: 0px; margin-bottom: 0px;" class="">Tl;dr: I would like to propose to drop these class variables and use Symbols instead. They are comparable like integers, and as they are flyweights, this should not be a performance issue either. Of course, #<span class="">generalCategoryOf: will have to keep returning numbers, but we could deprecate it and use a new #generalTagOf: in the future. Furthermore, this would also allow us to deal with later added category names (though I don't know whether this will ever happen).</span></div><div id="Signature" class=""><div id="divtagdefaultwrapper" dir="ltr" style="font-size: 12pt; font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols;" class=""><div name="divtagdefaultwrapper" style="font-family: Calibri, Arial, Helvetica, sans-serif; margin: 0px;" class=""><div class=""><div class="_rp_T4" id="Item.MessagePartBody"><div class="ms-font-color-neutralDark ms-font-weight-regular rpHighlightBodyClass rpHighlightAllClass _rp_U4" id="Item.MessageUniqueBody" style="font-family: wf_segoe-ui_normal, "Segoe UI", "Segoe WP", Tahoma, Arial, sans-serif, serif, EmojiFont;"><div dir="ltr" class=""><div id="divtagdefaultwrapper" class=""><font face="Calibri,Helvetica,sans-serif,EmojiFont,Apple Color Emoji,Segoe UI Emoji,NotoColorEmoji,Segoe UI Symbol,Android Emoji,EmojiSymbols" class=""><div id="Signature" class=""><div style="margin: 0px;" class=""><font style="font-family: Calibri, Arial, Helvetica, sans-serif, serif, EmojiFont;" class=""></font></div></div></font></div></div></div></div><div class="_rp_T4" id="Item.MessagePartBody"><br class=""></div><div class="_rp_T4" id="Item.MessagePartBody">Examples:</div></div></div></div></div><blockquote style="margin: 0px 0px 0px 40px; border: none; padding: 0px;" class=""><div class=""><div dir="ltr" style="font-size: 12pt; font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols;" class=""><div name="divtagdefaultwrapper" style="font-family: Calibri, Arial, Helvetica, sans-serif; margin: 0px;" class=""><div class=""><div class="_rp_T4" id="Item.MessagePartBody"><span class="">Unicode generalTagOf: $a asUnicode.
