Python `\x1b（B`做什么？

我是一个用户，最近，当我试图找出

term.bold（）

函数的内容时，我得到了以下输出：

\x1b[1m\x1b（B\x1b[m

我知道

\x1b[1m

和

\x1b[m

做了什么，但是

\x1b（B

做了什么？我试着打印它，但它似乎没有任何作用

提前感谢！

控制序列

\x1b（B

选择默认字符集ASCII。请参阅：

应该有帮助。提示：

B

不是转义序列的一部分。@Joachim Pileborg啊，我明白了……所以

\x1b（

设置默认字体。那么B代表什么呢？ ESC ( C Designate G0 Character Set (ISO 2022, VT100). Final character C for designating 94-character sets. In this list, 0 , A and B apply to VT100 and up, the remainder to VT220 and up. The VT220 character sets, together with the Portuguese character set are activated by the National Replacement Character controls. The A is a special case, since it is also activated by the VT300-control for British Latin-1 separately from the National Replacement Character controls. ... C = B -> United States (USASCII).
