unity text 文本符号显示问题与打字机效果的结合

问题1：unity text显示文本时，符号可能显示在某行的开头的位置
问题2：打字机效果没有适配问题1的脚本

解决方法：
问题1：通过遍历text组件每一行数据(第二行开始)，如果是符号，就在它之前的字符前添加换行符
问题2：适配上述脚本

脚本1 解决文本符号显示问题
TextSymbolFit.cs

public class TextSymbolFit : Text{/// <summary>/// 用于匹配标点符号/// </summary>private readonly string strRegex = @"\p{P}";/// <summary>/// 用于存储text组件中的内容/// </summary>private System.Text.StringBuilder MExplainText = null;/// <summary>/// 用于存储text生成器中的内容/// </summary>private IList<UILineInfo> MExpalinTextLine;protected override void OnPopulateMesh(VertexHelper toFill){base.OnPopulateMesh(toFill);StartCoroutine(MClearUpExplainMode(this, text));}private IEnumerator MClearUpExplainMode(Text _component, string _text){_component.text = _text;yield return new WaitForEndOfFrame();MExplainText = new System.Text.StringBuilder(_component.text);MExpalinTextLine = _component.cachedTextGenerator.lines;int mChangeIndex;// 从第二行开始进行检测for (int i = 1; i < MExpalinTextLine.Count; i++){try{if (MExpalinTextLine[i].startCharIdx >= _component.text.Length) continue;//首位是否有标点bool match = Regex.IsMatch(MExplainText.ToString()[MExpalinTextLine[i].startCharIdx].ToString(), strRegex);if (match){mChangeIndex = MExpalinTextLine[i].startCharIdx - 1;// 解决联系多个都是标点符号的问题for (int j = MExpalinTextLine[i].startCharIdx - 1; j > 0; j--){match = Regex.IsMatch(MExplainText.ToString()[j].ToString(), strRegex);if (match){mChangeIndex--;}else{break;}}MExplainText.Insert(mChangeIndex, "\n");}}catch (Exception e){Debug.LogException(e);}}_component.text = MExplainText.ToString();}}

脚本2，适配TextSymbolFit脚本
