Doesn't work well You can't just enter the code, you have to browse incomplete lists to find the code you want. Then they don't even appear. Fail.
OK, but could be much better. Showing the descriptive name (especially for non-visible characters) and having a "Favorites" feature would make this OK app much better.
Search doesn't work No way to find symbol by name. Too bad, but useless.
Android's Character Map Just like Windows has charmap.exe, Android has this app. If you need to find Unicode characters as easily as you would on Windows, this app is for you.
Wish the code page numbers were in the title-description would help to compare them by that
I use 00A0 a lot. This gives it to me, easily.
