Awesome To the people complaining about not being able to switch to this keyboard, try ENABLING it first, then you can make it your default keyboard. This is probably the most comprehensive unicode keyboard on the Android market. I just wish it had a regular, functional keyboard (with emojis). I'd pay money for a keyboard like that!
Very good, despite 2 minor drawbacks When writing Japanese text, I generally use the excellent GO Keyboard. However, I need occasionally to input single Japanese characters for which I only have the Unicode value. In this case, Unicode Keyboard definitely answers my needs and for me is a keeper :) I just wish there was an option to clear or pre-fill the keypad showing the last 9 characters used. Also, a key to delete already submitted characters without having to revert to my usual keyboard for this would be a welcome addition.
Don't bother It's way too much hassle to switch between input methods (if you can even find that setting) in order to use this, and you can't type ordinary text while the Unicode method is selected. Just too klunky to be useful. I recommend instead using 'Unicode Map' by David Madore which copies to the clipboard, and allows you to use your normal keyboard to edit the text to be copied. (I have no connection with the author of Unicode Map.)
Needs fixing! The whole of Unicode, by hex code, with an easy way to switch back to your primary keyboard. Hasn't been searchable for several Android versions now, though.
Gutted Wouldn't open...1st time instead of 'open', 'refund', then 2nd time 'uninstall', gonna give it one more go... c'mon. Samsung galaxy ace. Patience grasshopper... Aw it didn't work...hmn...
Of limited use above Android 4.3 Worked fine up to Android 4.2.2 but since OTA update to 4.3 and beyond the embedded search keyboard has stopped working so making finding symbols very tedious.
