嵌套ng-repeat内的角ng-bind-html

所以我在ng-repeat中有一个ng-repeat。内部ng-repeat引用“ recipe.ingredients中的项目”。问题在于，每个“项目”都有特殊字符，除非我使用ng-bind-html，否则它们不会呈现。但是，当我尝试使用ng-bind-html时，它不起作用。这是html：

这有效，但不能正确显示特殊字符（成分测量的分数）：

<div class="row" ng-repeat="recipe in recipes">
    <h1 class='title'> {{ recipe.title }} </h1>
    <div class="col-md-5">
        <div class="list-group">
            <div class="list-title">Ingredients</div>
            <p class="list-group-item" ng-repeat="item in recipe.ingredients">{{item}}</p>
        </div>
    </div>
</div>

我尝试使用ng-bind-html代替（不起作用）：

<div class="row" ng-repeat="recipe in recipes">
    <h1 class='title'> {{ recipe.title }} </h1>
    <div class="col-md-5">
        <div class="list-group">
            <div class="list-title">Ingredients</div>
            <p class="list-group-item" ng-repeat="item in recipe.ingredients" ng-bind-html="item"></p>
        </div>
    </div>
</div>

ng-repeat中“项目”的示例：

       {
            id: 1,
            img: "images/beefThumbnail.jpg",
            title: "Potatoes Supreme",
            servings: "Servings: 8 - 10",
            ingredients: [
                "6 medium potatoes, peeled",
                "Salt",
                "½ cup butter or margarine, melted",
                "2 cups shredded Cheddar cheese",
                "⅓ cup chopped green onion",
                "1 pint sour cream",
                "¼ teaspoon pepper",
                "½ teaspoon salt"
            ],
            directions: [
                "Oven 350°",
                "Cook potatoes in boiling salted water until done",
                "The next day grate potatoes coarsely",
                "Mix with remaining ingredients",
                "Place in shallow 1.5 or 2 quart baking dish and bake about 35 minutes"
            ]
        },//end potatoesSupreme
