encoding - 如何对非 ASCII 字符串和非整数进行 Bencode？

Question

根据bencoding specification :

Bencoded strings are encoded as follows: <string length encoded in base ten ASCII>:<string data>, or key:value Note that there is no constant beginning delimiter, and no ending delimiter.

Example: 4:spam represents the string "spam"
Example: 0: represents the empty string ""

Integers are encoded as follows: i<integer encoded in base ten ASCII>e The initial i and trailing e are beginning and ending delimiters. You can have negative numbers such as i-3e. Only the significant digits should be used, one cannot pad the Integer with zeroes. such as i04e. However, i0e is valid.

Example: i3e represents the integer "3"

我的问题:

问题 1:我应该如何对包含非 ascii 字符的字符串进行 bencode？例如:mûrier或die höhe Zeit我应该使用 UTF-8 将这样的字符串转换为字节序列吗？编码，还是另一种？它如何应用于规范？

问题2:如何对非整数进行Bencode，例如1.0002910或-0.0049172 ？

Answer 1

1. 根据规范，“所有字符串值均采用 UTF-8 编码。”
2. 不属于规范范围；显然不需要。
