to_yaml 中引号的换行不一致

Question

介绍

在下面的示例中，您可以看到 header 和第 1 节和第 11 节已作为普通值放入 yaml 中，但第 2 节和第 8 节已用单引号括起来。 这似乎发生在to_yaml阶段，因为在 hash 中一切看起来都不错。 （我不是简单地加载 yaml 并将其转换回来，这只是为了简化示例）

我试过的

我试过看看是否有任何特殊字符会引起混淆，但没有任何运气。 例如，在单词vehicle's有一个卷曲撇号而不是一个直撇号' ，但在所有部分都可以找到。 isn't in section 2 有直撇号。 我尝试在不同的部分系统地添加/删除每种类型的撇号，看看这是否会产生任何影响，但它没有

Answer 1

• 第 1 列，第 2 节，文本包含一个尾随空格。
• 第 2 列，第 8 节，文本包含一个:字符，后跟一个空格。

规范说：

普通（未加引号）样式没有识别指示符，也没有提供 escaping 的形式。 因此，它是最易读、最有限和最上下文敏感的风格。 除了受限字符集之外，纯标量不得为空，也不得包含前导或尾随空白字符。 只能在空格字符被非空格包围的地方打断一条长的平线。

...

纯标量绝不能包含“:”和“#”字符组合。 这样的组合会导致映射键的歧义：值对和注释。 此外，在流 collections 内部，或用作隐式键时，纯标量不得包含“[”、“]”、“{”、“}”和“,”字符。 这些字符会导致流集合结构的歧义。
