Question

如何转换以下字符串文字：

token = "\x1b(0l\x1b(BHeader"

分为：

"┌Header"

我从库中接收文字Unix框图字符，需要转换为unicode进行单元测试。

Answer 1

这是VT-100备用字符集（在编辑问题主题之前不太明显）。序列assemblyMergeStrategy in assembly := { ^ C:\Users\sreer\Desktop\workspace\cool\build.sbt:14: error: not found: value assembly assemblyMergeStrategy in assembly := { ^ C:\Users\sreer\Desktop\workspace\cool\build.sbt:15: error: not found: value PathList case PathList("META-INF", xs @ _*) => MergeStrategy.discard ^ C:\Users\sreer\Desktop\workspace\cool\build.sbt:15: error: star patterns must correspond with varargs parameters case PathList("META-INF", xs @ _*) => MergeStrategy.discard ^ C:\Users\sreer\Desktop\workspace\cool\build.sbt:15: error: not found: value MergeStrategy case PathList("META-INF", xs @ _*) => MergeStrategy.discard ^ C:\Users\sreer\Desktop\workspace\cool\build.sbt:16: error: not found: value MergeStrategy case x => MergeStrategy.first ^ [error] Type error in expression将编码更改为备用集，序列esc ( 0将其更改回来。只有少数几个这样的字符被映射。这是映射。

esc ( B

要进行转换，您必须设置一个dict，将这些代码映射到相应的Unicode代码点并自行转换。

@BoarGules是正确的。这是我解码字符串的解决方案：

vt_100_mapping = {
    '0x71': '─',
    '0x74': '├',
    '0x75': '┤',
    '0x76': '┴',
    '0x77': '┬',
    '0x78': '│',
    '0x6a': '┘',
    '0x6b': '┐',
    '0x6c': '┌',
    '0x6d': '└',
    '0x6e': '┼',
}

from itertools import groupby

def decode_vt_100(iterable, default_set='(B', alt_set='(0'):
    for is_escape, group in groupby(iterable, lambda _: _ =='\x1b'):
        if is_escape:
            continue

        characters = ''.join(group)

        if characters.startswith(default_set):
            yield characters[len(default_set):]

        elif characters.startswith(alt_set):
            for character in characters[len(alt_set):]:
                yield vt_100_mapping[hex(ord(character))]

>>> print(''.join(decode_vt_100("\x1b(0l\x1b(BHeader")))
┌Header
