从十六进制字符串表示创建原始 unicode 字符
Create raw unicode character from hex string representation
给定 Unicode 字符的字符串十六进制表示,我想打印它所代表的 Unicode 字符
julia> s1, s2 = raw"\u0041", raw"\x41"
julia> println(s1,' ', s2)
\u0041 \x41
相反,我希望它打印“A A”
用例:
对于演示,我想遍历一系列值并打印从十六进制表示到 Unicode 的映射:
for ii = 0x0021 : 0x007f
hex_rep = string(ii, base=16)
unicode = raw"\u" * lpad(hex_rep, 4, '0')
println(hex_rep, " -> ", unicode)
end
你可以这样做:
julia> Char.(0x0021 : 0x007f)
95-element Vector{Char}:
'!': ASCII/Unicode U+0021 (category Po: Punctuation, other)
'"': ASCII/Unicode U+0022 (category Po: Punctuation, other)
'#': ASCII/Unicode U+0023 (category Po: Punctuation, other)
⋮
'}': ASCII/Unicode U+007D (category Pe: Punctuation, close)
'~': ASCII/Unicode U+007E (category Sm: Symbol, math)
'\x7f': ASCII/Unicode U+007F (category Cc: Other, control)
对于其他情况考虑使用上述unescape_string
