【Unity学习笔记】UGUI输入框中将中文设置为两个字节

byte[] tempByte;    //存储字节数组
public int upperLimit = 12  //限制字节数
public InputField _inputField;

void Start()
{
//添加回调
_inputField.onValueChanged.AddListener(CheckByteCount);
}
void CheckByteCount(string inputText) {
inputText = inputText.Replace(" ", "");    //去掉空格
tempByte = Encoding.GetEncoding("GB2312").GetBytes(inputText.ToCharArray());

if (tempByte.Length >= upperLimit)
_inputField.characterLimit = inputText.Length;
else
//在字节数小于限制时重现设置输入上限
_inputField.characterLimit = upperLimit;

_inputField.text = inputText;
}
