TT, You clearly know more about this than myself. When I read about "Mathematical Alphanumeric Symbols" I keep seeing references not to be used as "prose text". There is good reason for this as they look like normal text with a font style applied but they are not the same. However it seems to me this very reason may be its very value, at least in tiddlywiki, The tag π΅π²πΌπ½ <https://tiddlywiki.com/#%F0%9D%93%B5%F0%9D%93%B2%F0%9D%93%BC%F0%9D%93%BD> is different to the tag list macros can be written with the name π΅π²πΌπ½ <https://tiddlywiki.com/#%F0%9D%93%B5%F0%9D%93%B2%F0%9D%93%BC%F0%9D%93%BD> and more.
We often talk about semantics and and using plan "English" language for tiddlers, macros, fields etc... Yes there are issues with the front end user accessing these without knowledge of these different character set. But when developing a tiddlywiki it could have some real advantages. For example I could define tiddlers for tags and fields. For example I could code a method to define tag tiddlers with the equivalent in a different character set. I can have "same name" multiple times, each performing a different purpose. Once created they can be applied from a list, although searched only if you can copy the alternate character text. I have followed the various leads shared with me but I am yet to find a way to exchange current alphanumeric's on my keyboard with those from the other mathematical alphanumeric sets, with a setting, so I can simply type as if is was standard. Upper and lower case! 26x2+10numerals or 62 alphanumerics per set. Yes some of these solutions provide a path to this outcome by allowing new mappings however, that is a lot of work that could have being automated in a given solution. There are multiple sets of alphanumerics so this will take a lot of time if I can't find such a specific solution. I would have thought this had being done before, or am I at the bleeding edge? I will test it in a wider set of circumstances but they are resolving in Chrome and Firefox without alteration. Although it is true depending how I design it may not matter to end users if such fonts are only used behind the scenes.
