## What is YooniKey?

Are you frequently wanting to type characters that aren't in standard keyboards? I know I was, and didn't want to pay extra just to get to the characters I needed. So I wrote YooniKey, a full Unicode® browser application and an embedded keyboard that can be used by any application. Both the app and the keyboard offer a searchable list of Unicode® code blocks and code points.

Keyboard highlights:
⁍Quickly jump to any code block, sorted by name or natural position.
⁍When searching in the keyboard, a simple ASCII keyboard appears that allows you to type the limited characters allowed in code point names.
⁍See and type favorite and recently used code points.
⁍Long-press on a code point for more information about it. Releasing with your finger inside the info balloon will filter on the tapped code point's related code points. That makes for fast, simple exploration without having to visit the app!

App highlights:
⁍Quickly jump to any code block, sorted by name or natural position.
⁍Customize the index shown on the right for even faster access to your favorite code blocks.
⁍Tap on a code point for more information about it, include its hex value, name, aliases, and related characters.
⁍Long-press a code point to add it to or remove it from favorites or to filter on its related code points.
⁍Long-press on a related character in the info area to look up that code point, include its hex value, name, and related characters.
⁍Tap code points to enter them into the edit field, then tap the Copy to Pasteboard button so your text can be pasted elsewhere.
⁍Styled alphabet converter makes it easy to create custom text in assorted typefaces found in the Mathematical Alphanumeric Symbols code block.

I’ve been struggling to find the character I want and about 8,000 of these glyphs appear as a ? Box, which makes it harder but overall, ⭐️3½.

**Developer response:** Please give me an example of which glyphs, providing either the code point number or the full name.
