using UnityEngine;
using MLTool;
public class SampleCode : MonoBehaviour
{
    [SerializeField]
    private TextAsset lines = null;

Return the target text content with target language,

using UnityEngine;
using MLTool;
public class SampleCode : MonoBehaviour
{
    [SerializeField]
    private TextAsset lines = null;

    private void Start()
    {
        WordDic.Init("en", lines.text);
        Debug.Log(WordDic.Get("key1"));
    }
}

public static void Register(IMLText mLText)
