This encoding scheme makes it possible to encode an ASCII character with one byte, and a non-ASCII character with multiple (up to 4) bytes.

这个编码方案可以用一个字节对 ASCII 字符进行编码，用多个字节（最多 4 字节）对非 ASCII 字符进行编码。

Base64 encoding transforms arbitrary data values into printable ASCII characters by using one ASCII character to represent each six bits of the original data.

通过对原始数据中的每六位使用一个ASCII字符来表示，Base64编码可以将任意的数据值转换为可打印的ASCII字符。

ASCII streams, for ASCII character data.

ascii流，用于ASCII字符数据。

You just need to express in ASCII character, one at a time, and these brave souls are simply going to spell something out for us to hammer home this point of binary.

你们只需要每人代表一个ASCII码，这些勇敢的小伙子们就是想,清楚的让大家理解二进制原理。

> But if you actually do the math, those zeros and ones translate to an ASCII character which is D which is gonna be a 65, 66, 67, 68 would be the letter D.

>，你们自己算算看,把这些0和1转换成D对应的ASCII码,那么就是，65，66，67，68，对，68对应于“D“
