Unity-uiinput Custom Limit input characters

The Uiinput component as shown in

The uiinput can be used to create an input box that comes with 6 restrictions, as shown in

The last type of Alphabet Int Chinese is my custom, which restricts the input of letters, numbers, Chinese characters, such as nicknames, and can use this setting.

Custom restriction input code to modify Uiinput

First, find the validation attribute

1  Public enumValidation2     {3 None,4 Integer,5 Float,6 Alphanumeric,7 Username,8 Name,9Alphabetintchinese,//CustomTen}

Add the name of our custom type in which I add the Alphabetintchinese
Find Validate this function
