How to disable the filtering of emoji characters

hi

In the generated Xcode project you can go into /Classes/UI/Keyboard.mm and change the define for FILTER_EMOJIS_IOS_KEYBOARD. Setting this flag to 0 will allow emoji symbols to be entered using the keyboard.

 

Hey,

You can try defining a preprocessor symbol for the Xcode project, similar to what is described here: http://stackoverflow.com/questions/367368/how-to-define-a-preprocessor-symbol-in-xcode

A script like the following should work:

Code (CSharp):

1. using UnityEditor;
2. using UnityEditor.Callbacks;
3. using System.Collections;
4. using UnityEditor.iOS.Xcode;
5. using System.IO;
6.  
7. public class XcodePostProcessSteps {
8.  
9.  
10.     // A post process step to modify the generated Xcode project, disabling the emoji filter
11.     [PostProcessBuild]
12.     public static void DisableEmojiFilter(BuildTarget buildTarget, string pathToBuiltProject) {
13.  
14.         // Only continue if we're building for iOS
15.         if (buildTarget == BuildTarget.iOS) {
16.  
17.             // Get Xcode project
18.             string pbxprojPath = pathToBuiltProject + "/Unity-iPhone.xcodeproj/project.pbxproj";
19.             PBXProject proj = new PBXProject();
20.             proj.ReadFromString(File.ReadAllText(pbxprojPath));
21.  
22.             // Set GCC_PREPROCESSOR_DEFINITIONS to define FILTER_EMOJIS_IOS_KEYBOARD=0
23.             string target = proj.TargetGuidByName("Unity-iPhone");
24.             proj.SetBuildProperty(target, "GCC_PREPROCESSOR_DEFINITIONS", "FILTER_EMOJIS_IOS_KEYBOARD=0");
25.  
26.             // Write changes to the Xcode project
27.             File.WriteAllText(pbxprojPath, proj.WriteToString());
28.  
29.         }
30.     }
31. }

I hope this helps!
