US-ASCII is upwards-compatible with UTF-8 (an US-ASCII string is also a UTF-8 string, see [RFC 3629]), and UTF-8 is therefore appropriate if compatibility with US-ASCII is desired.

US-ASCII 对 UTF-8 向上兼容（US-ASCII 字符串也是 UTF-8 字符串，参见 [RFC 3629]），因此如果需要与 US-ASCII 保持兼容，UTF-8 非常合适。

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。

Now for the hacker edition, if you are feeling up to a bit more of a challenge you'll find that when you run the game, one it's not all that hard to use some ASCII art just make it a little fancier as the teaching fellow who implemented this solution did.

对于升级版，如果你能应付更大的,挑战，你会发现当你在玩这个游戏时，用一些字符画把它做得,比那些教学人员做的更有新意,并不是那么困难。

Well it turns out a bunch of years ago people just decided that if we have the ability to express numbers and we actually care about expressing letters of the alphabet, well we just need some kind of mapping between one and the other, ASCII and so thus was born what's generally called the ASCII.

结果证实，数年前,人们觉得如果我们,有数字表达能力,而我们真正在乎其实是字符的表达，那么我们就需要数字和字符的某种对应关系，于是就有了俗称的。
