从十六进制字符串表示形式中创建RAW UNICODE字符

发布于 2025-01-20 04:15:20 字数 399 浏览 1 评论 0原文

给定一个Unicode字符的字符串十六进制表示，我想打印其代表的Unicode字符

julia> s1, s2 = raw"\u0041", raw"\x41"
julia> println(s1,' ', s2)
\u0041 \x41

，我希望它打印“ A” A'

用例：对于演示，我想循环多个值，并将地图从十六进制表示到Unicode：

for ii = 0x0021 : 0x007f
    hex_rep = string(ii, base=16)
    unicode = raw"\u" * lpad(hex_rep, 4, '0')
    println(hex_rep, " -> ", unicode)
end

原文

Given the string hex representation of a Unicode character, I would like to print the Unicode character it represents

julia> s1, s2 = raw"\u0041", raw"\x41"
julia> println(s1,' ', s2)
\u0041 \x41

Instead, I want it to print "A A"

Use Case:
For a demo, I would like to loop over a range of values and print a map from the hex representation to the Unicode:

for ii = 0x0021 : 0x007f
    hex_rep = string(ii, base=16)
    unicode = raw"\u" * lpad(hex_rep, 4, '0')
    println(hex_rep, " -> ", unicode)
end

您可以这样做：

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，请考虑使用上述 unescape_string

You can just do:

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)

For other cases consider using the forementioned unescape_string
