[SOLVED] Disable Emoji in mobile keyboard

Hi everybody ,

Today i'm getting stuck with emoji on mobile keyboard

i've start to create an apk who you can send encrypted text message to your friends from database but i get error if my friend send me a text with emoji

the encryption fail and i get error .

Do you know how can i disable emoji from mobile keyboard ?
or if you know another way to get it work ?
like filter the UI text ?
any help are welcome .

thanks by advance for your time .

 

Your best bet is to filter out the unicode on the input side rather than the keyboard side. This SO answer explains it better than I can:

thanks for the reply but i dont really understand in your link the code

i think i can find something with characters filter or content type in inputfield .

if i put content type Name in input field i get special character blocked (like i want) but all words get first letters with capitalisation

and if i choose content type password all is good except the text is hidden by stars

please help me to find a way .

 

You're still looking at the keyboard side. I'm talking about the input validation side. Check the characters that are being input by the user. If it looks like an emoji, remove it.

 

i find another way ,:

i set the content type as password ,
duplicate the Text value from the inputfield and set it to a new Text.UI

so now when i write on the mobile keyboard emoji's gone and i can see what i write because stars are removed

 

Hi, in this case, the stars will be removed from the in-game input field but mobile keyboard input box will still show stars isn't it?

 

any solution ?

 

Came through this today while trying to find a way to disable Emojis on an InputField. Came up with the solution below, which seems to work well so far.

Code (CSharp):

1.  
2. // Add the onValidateInput delegate to your Input Field (This assumes you are not using any Character Validation in your Input Field already)
3. private char OnValidateInput(string text, int charIndex, char addedChar)
4. {
5.             // Filter out the Unicode categories you want (example below), keep in mind that, while this can filter out Emojis, it can also filter out chars you might want to keep (e.g. Asiatic languages, which I don't need to care about right now), so this is not a perfect solution.
6.             var unicodeCategory = char.GetUnicodeCategory(addedChar);
7.  
8.             switch (unicodeCategory)
9.             {
10.                 case UnicodeCategory.OtherSymbol:
11.                 case UnicodeCategory.Surrogate:
12.                 case UnicodeCategory.ModifierSymbol:
13.                 case UnicodeCategory.NonSpacingMark:
14.                     // Refer to https://www.compart.com/en/unicode/ for a comprehensive list of Unicode categories and chars
15.                     return char.MinValue;
16.                 default:
17.                     return addedChar;
18.             }
19. }
20.  

 

Thank you, solved my problem.
