UnicodePad is the perfect app for finding the Unicode code for any character you want. Similarly, you can use this app to type any character by copying it to your clipboard and then pasting it anywhere you want.
If you press for two seconds on any of the UnicodePad characters, you'll see a tab with additional information on the character in question. You can see it in a larger size, and you can also check its Unicode code. You can even copy it to your clipboard or mark it as a favorite. When you mark a character as a favorite, you can find it more easily in the future.
UnicodePad is a pretty useful app, thanks to which you can find any character you want no matter the language. To see some characters, however, you'll need to have certain fonts installed.
