digit
在 vim 中使用 <C-v>*** 可以输入不常用字符, 具体 *** 可参考如下:
| first char | mode | max nr of chars | example | max value |
|---|---|---|---|---|
| (none) | decimal | 3 | <C-v>122 | 255 |
| o or O | octal | 3 | <C-v>o033 | 377 (255) |
| x or X | hexadecimal | 2 | <C-v>x2a / <C-v>X2a | ff (255) |
| u | hexadecimal | 4 | <C-v>u002a | ffff (65535) |
| U | hexadecimal | 8 | <C-v>U0000002a | 7fffffff (2147483647) |

ASCII 与 unicode 关系
- 标准的 ASCII 只有 128 个字符, Unicode 是标准 ASCII 的超集, 是完全兼容的
- 除了标准 ASCII, 还有一个 Extended ASCII, 有 256 个字符, Extended ASCII 的 128~255 字符是与 Unicode 不兼容的; 出于通用化考虑, Extended ASCII 可以不用考虑了
