Detected UTF-16-encoded Basic Latin-only text without a byte order mark and without a transfer protocol-level declaration. Encoding this content in UTF-16 is inefficient and the character encoding should have been declared in any case.
检测到 UTF-16 编码的拉丁字母文本，没有字节顺序标记也没有传输协议基本声明。用 UTF-16 编码这种内容是低效率的，无论如何都应该对字符编码予以声明。
