Please add a Unicode search field to the glyphs panel to make it easier to see glyphs if you know their ID. A search by name would also be very useful but I know that does rely on the vendor having identified them correctly if they are in special use (and outside of the predefined names).
If the field could be prefixed with "U+" then all a user would need to type into the field would be eg: "00A9" to highlight the Copyright symbol (U+00A9).

Please allow us to search for glyphs in the panel, either using the unicode or via the name of the symbol. It is excruciating having to scroll through hundreds of characters hoping that your font supports the correct one.

This is valuable to me because I am a graduate student researcher and I design figures for presentations in Illustrator, but it is challenging to write mathematical symbols without a simple search feature. For example, the partial derivative symbol or the gradient symbol is not available in all fonts, but if I want to find it, I have to search through every line.

Please add a search feature in the Glyphs panel by entering the unicode character, similar to InDesign

In the glyph panel, please add a search field like the one in InDesign. This improves workflow a lot by making it easier to find a particular glyph/character within a font. I especially find it handy when working with Font Awesome to add icons to my work. Font Awesome glyphs all have searchable names, so this works really well in InDesign. It looks like other fonts have searchable names for their characters as well. In InDesign, I was able to search on "del" to find the Delta character in the Garamond font. It's soooo much faster than scrolling through the grid. I would love to have this same workflow efficiency in Illustrator (and Photoshop too).

The Glyph windows is completely, absolutely, omnipresently useless. It serves you nothing else but frustration. What good is a computer for if you cannot use it to perform a simple search? Glyph window without search capabilities is beyond comprehension. The most simple stuff a computer can do for you is search through things and you dare to present a window with thousands of glyphs for the user to squint and manually search it. How insulting! Get rid of ti, and the team behind it too, they know nothing about UX nor software development.

Searching for the right glyph is a true chore, especially with all glyph fonts. Please add the capability to search for glyphs.
