How to disable the filtering of emoji characters

Unity Engine

In Unity 5.3.4 p1 release notes I see this:
iOS: Added a compile flag in the trampoline code in order to allow the user to disable the filtering of emoji characters.

How exactly I can add this compile flag, and what is this flag?

hi :slight_smile:

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.

Hi Ryan, Do you know if there a way to do this via the Xcode Manipulation API in a Post process?

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:

using UnityEditor;
using UnityEditor.Callbacks;
using System.Collections;
using UnityEditor.iOS.Xcode;
using System.IO;

public class XcodePostProcessSteps {


    // A post process step to modify the generated Xcode project, disabling the emoji filter
    [PostProcessBuild]
    public static void DisableEmojiFilter(BuildTarget buildTarget, string pathToBuiltProject) {

        // Only continue if we're building for iOS
        if (buildTarget == BuildTarget.iOS) {

            // Get Xcode project
            string pbxprojPath = pathToBuiltProject + "/Unity-iPhone.xcodeproj/project.pbxproj";
            PBXProject proj = new PBXProject();
            proj.ReadFromString(File.ReadAllText(pbxprojPath));

            // Set GCC_PREPROCESSOR_DEFINITIONS to define FILTER_EMOJIS_IOS_KEYBOARD=0
            string target = proj.TargetGuidByName("Unity-iPhone");
            proj.SetBuildProperty(target, "GCC_PREPROCESSOR_DEFINITIONS", "FILTER_EMOJIS_IOS_KEYBOARD=0");

            // Write changes to the Xcode project
            File.WriteAllText(pbxprojPath, proj.WriteToString());

        }
    }
}

I hope this helps! :slight_smile:
