Traditional Chinese doesn't fallback as expected

I have set up two Chinese languages as:


When an Android phone is set to Traditional Chinese (Hong Kong), opening the app first time it fallbacks to Simplified Chinese incorrectly.

Traditional Chinese (Taiwan) is working as expected though.

I2 Localization.2.8.13f1
Unity 2019.4.20f1

Sadly the developer seems absent for 2+ weeks and hope he is fine and will take a look on this matter soon...

Finally, I found the issue, when "zh-HK" couldn't be found, it simply falls back to the FIRST Chinese, in my case is "zh-CN": LanguageSourceData_Languages (line 55):
public int GetLanguageIndexFromCode( string Code, bool exactMatch=true, bool ignoreDisabled = false)
		{
            for (int i = 0, imax = mLanguages.Count; i < imax; ++i)
            {
                if (ignoreDisabled && !mLanguages[i].IsEnabled())
                    continue;

                if (string.Compare(mLanguages[i].Code, Code, StringComparison.OrdinalIgnoreCase) == 0)
                    return i;
            }

			if (!exactMatch)
			{
                // Find any match without using the Regions
                for (int i = 0, imax = mLanguages.Count; i < imax; ++i)
                {
                    if (ignoreDisabled && !mLanguages[i].IsEnabled())
                        continue;

                    if (string.Compare(mLanguages[i].Code, 0, Code, 0, 2, StringComparison.OrdinalIgnoreCase) == 0)
                        return i;
                }
			}

			return -1;
		}

GetLanguageIndexFromCode ( "zh-HK", false, true ) returns "zh-CN"


A workaround (may not cover all the cases) is always put Chinese (Tranditional) before Chinese (Simplfied):



A code fix should be, put cases that return the correct fallback, e.g. zh-HK, zh-MO to zh-TW; zh-SG to zh-CN as described here .
