由于原来富文本不区分字符和数字和汉字的大小，统一按照一个宽度来计算，这样会发现带有数字的行不排满就换行的错误所以增加了以下代码

在UIRichText.js文件中 修改函数_handleTextRenderer(),增加绿色部分的代码

_handleTextRenderer: function (text,fontNameOrFontDeffontSizecolor) {
    if(text === "")
        return;

    "\n"){ //Force Line Breaking
        this._addNewLine()            }

    var textRenderer = fontNameOrFontDef instanceof cc.FontDefinition ? new cc.LabelTTF(textfontNameOrFontDef) : fontSize)var textRendererWidth = textRenderer.getContentSize().widththis._leftSpaceWidth -= textRendererWidthif (_leftSpaceWidth < 0) {
        var overstepPercent = (-_leftSpaceWidth) / textRendererWidthvar curText = textvar stringLength = curText.lengthvar leftLength = stringLength * (1 - overstepPercent)var leftWords = curText.substr(0leftLength)        //2017-7-8 修改引擎 富文本每行计算宽度（原来是不区分字符和数字的）

 if(textRenderer && textRenderer._renderCmd && textRenderer._renderCmd._measure){
        var textWidth = textRenderer._renderCmd._measure(leftWords);        var maxCheckTurn = 0;        while(textWidth < this._customSize.width && leftLength < stringLength && maxCheckTurn <= 100){            leftLength++;            leftWords = curText.substr(0,leftLength);            textWidth = textRenderer._renderCmd._measure(leftWords);            maxCheckTurn++;        }        maxCheckTurn = 0;        while(textWidth > this._customSize.width && leftLength > 1 && maxCheckTurn <= 100){            leftLength--;            leftWords = curText.substr(0,leftLength);            textWidth = textRenderer._renderCmd._measure(leftWords);            maxCheckTurn++;        }        maxCheckTurn = 0;

}     }
//修改完毕

var cutWords = curText.substr(leftLengthcurText.length - 1)var validLeftLength = leftLength > if(_lineBreakOnSpace){
            var lastSpaceIndex = leftWords.lastIndexOf(' ')            leftLength = lastSpaceIndex === -1 ? leftLength : lastSpaceIndex+1             cutWords = curText.            validLeftLength = leftLength > 0 && cutWords !== " "        }

        if (validLeftLength) {
            var leftRenderer = null            if( fontNameOrFontDef FontDefinition)
            {
                leftRenderer = LabelTTF(leftWords.fontNameOrFontDef)                leftRenderer.setOpacity(fontNameOrFontDef.fillStyle.a); //TODO: Verify that might not be needed...  }else{
                leftRenderer =  setColor(color)setOpacity(color.            }
            _pushToContainer(leftRenderer)this._handleTextRenderer(cutWordscolor)    } else {
        FontDefinition) {
            textRenderer.else {
            textRenderer.            textRenderer.        }
        _pushToContainer(textRenderer)    }
