问题描述
我有一个十六进制的ASCII图A，并且在A中有很多控制图，像这样
A = 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
我执行命令
echo "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" |python -c "s = raw_input().decode('hex'); print(str(s))"
(reverse-i-search)`ls': ls /opt/
我得到的结果是“（reverse-i-search）`ls'：ls / opt /”，但是结果中有许多控制图。当我这样执行时

结果与A相同。
如何从ASCII图表A中获取不包含控制ASCII图表的真实字符串“（reverse-i-search）`ls'：ls / opt /”
echo -e "(reverse-i-search)\`ls': ls /opt/" | python -c "print(raw_input().encode('hex'))"
