如何从字符串中删除表情符号

时间:2022-09-15 13:06:54

My problem is to remove emoji from a string, but not CJK (Chinese, Japanese, Korean) characters from a string using regex. I tried to use this regex:

我的问题是从字符串中删除表情符号,而不是使用regex从字符串中删除CJK(中文、日文、韩文)字符。我试着使用这个regex:

REGEX = /[^\u1F600-\u1F6FF\s]/i

This regex works fine except it also detects the Chinese, Japanese and Korean character where I need those characters. Any idea how to solve this issue?

这个regex可以正常工作,但是它还可以检测到需要这些字符的中国、日本和韩国字符。你知道怎么解决这个问题吗?

Karol S already provided a solution, but the reason might not be clear:

Karol S已经提供了一个解决方案,但原因可能并不清楚:

"\u1F600" is actually "\u1F60" followed by "0":

“\u1F600”实际上是“\u1F60”,然后是“0”:

"\u1F60"    # => "ὠ"
"\u1F600"   # => "ὠ0"

You have to use curly braces for code points above FFFF:

您必须使用花括号,以在FFFF之上的代码点:

"\u{1F600}" #=> "????"

Therefore the character class [\u1F600-\u1F6FF] is interpreted as [\u1F60 0-\u1F6F F], i.e. it matches "\u1F60", the range "0".."\u1F6F" and "F".

因此字符类[\u1F600-\u1F6FF]被解释为[\u1F60 -\u1F6F],即它匹配"\u1F60",范围"0"。\ u1F6F”和“F”。

Using curly braces solves the issue:

使用大括号解决了这个问题:

/[\u{1F600}-\u{1F6FF}]/

This matches (emoji) characters in these unicode blocks:

它匹配这些unicode区块中的(表情符号)字符:


You can also use unpack, pack, and between? to achieve a similar result. This also works for Ruby 1.8.7 which doesn't support Unicode in regular expressions.

您还可以使用开箱,打包,以及之间?取得类似的结果。这也适用于Ruby 1.8.7,在正则表达式中不支持Unicode。

s = 'Hi!????'
#=> "Hi!\360\237\230\200"

s.unpack('U*').reject{ |e| e.between?(0x1F600, 0x1F6FF) }.pack('U*')
#=> "Hi!" 

Regarding your Rubular exampleEmoji are single characters:

关于你的小红帽例子——表情符号是单个字符:

"????".length  #=> 1
"????".chars   #=> ["????"]

Whereas kaomoji are a combination of multiple characters:

kaomoji是多种字符的组合:

"^_^".length #=> 3
"^_^".chars  #=> ["^", "_", "^"]

Matching these is a very different task (and you should ask that in a separate question).

匹配这些是一个非常不同的任务(您应该在另一个问题中问这个问题)。

str = "I am a string with emoji ???????????????????????????????? and other Unicode characters 比如中文."
str.gsub regex, ''
# "I am a string with emoji  and other Unicode characters 比如中文."

Other Unicode characters, such as Asian characters, are preserved.

其他Unicode字符(如亚洲字符)将被保留。

EDIT: I udpated the regex to exclude ASCII numbers and symbols. See comments for details.

I am using one based on this script.

我正在基于这个脚本使用一个。

 def strip_emoji(text)
    text = text.force_encoding('utf-8').encode
    clean = ""

    # symbols & pics
    regex = /[\u{1f300}-\u{1f5ff}]/
    clean = text.gsub regex, ""

    # enclosed chars 
    regex = /[\u{2500}-\u{2BEF}]/ # I changed this to exclude chinese char
    clean = clean.gsub regex, ""

    # emoticons
    regex = /[\u{1f600}-\u{1f64f}]/
    clean = clean.gsub regex, ""

    #dingbats
    regex = /[\u{2702}-\u{27b0}]/
    clean = clean.gsub regex, ""

REGEX = /[^\u{1F600}-\u{1F6FF}\s]/

or

REGEX = /[\u{1F600}-\u{1F6FF}\s]/
REGEX = /[\u{1F600}-\u{1F6FF}]/
REGEX = /[^\u{1F600}-\u{1F6FF}]/

because your original regex seems to indicate you try to find everything that is not an amoji and not a whitespace and I don't know why would you want to do it.

因为您最初的regex似乎表明您试图查找所有不是amoji也不是空格的内容,我不知道您为什么要这样做。

Also:

另外:

  • the emoji are 1F300-1F6FF rather than 1F600-1F6FF; you may want to change that

    表情符号是1F300-1F6FF,而不是1F600-1F6FF;你可能想要改变它。

  • if you want to remove all astral characters (for example you deal with a software that doesn't support all of Unicode), you should use 10000-10FFFF.

    如果您想要删除所有的星体字符(例如,您要处理一个不支持所有Unicode的软件),您应该使用10,000 - 10ffff。

EDIT: You almost certainly want REGEX = /[\u{1F600}-\u{1F6FF}]/ or similar. Your original regex matched everything that is not a whitespace, and not in range 0-\u1F6F. Since spaces are whitespace, and English letters are in range 0-\u1F6F, and Chinese characters are in neither, the regex matched Chinese characters and removed them.

编辑:您几乎肯定想要REGEX = /[\u{1F600}-\u{1F6FF}]/或类似的。您的原始regex匹配了所有非空白、不在0-\u1F6F范围内的内容。由于空格是空格,英文字母在0-\u1F6F范围内,而中文字符在两者都不在范围内,所以regex会匹配并删除它们。

Instead of removing Emoji characters, you can only include alphabets and numbers. A simple tr should do the trick, .tr('^A-Za-z0-9', ''). Of course this will remove all punctuation, but you can always modify the regex to suit your specific condition.

你不能删除表情符号,你只能包括字母和数字。一个简单的tr应该做的诀窍,.tr(“^ A-Za-z0-9“,”)。当然,这将删除所有的标点符号,但是您始终可以修改regex以适应您的特定条件。

str = "I am a string with emoji ???????????????????????????????? and other Unicode characters 比如中文."
str.gsub regex, ''
# "I am a string with emoji  and other Unicode characters 比如中文."

Other Unicode characters, such as Asian characters, are preserved.

其他Unicode字符(如亚洲字符)将被保留。

EDIT: I udpated the regex to exclude ASCII numbers and symbols. See comments for details.

I am using one based on this script.

我正在基于这个脚本使用一个。

 def strip_emoji(text)
    text = text.force_encoding('utf-8').encode
    clean = ""

    # symbols & pics
    regex = /[\u{1f300}-\u{1f5ff}]/
    clean = text.gsub regex, ""

    # enclosed chars 
    regex = /[\u{2500}-\u{2BEF}]/ # I changed this to exclude chinese char
    clean = clean.gsub regex, ""

    # emoticons
    regex = /[\u{1f600}-\u{1f64f}]/
    clean = clean.gsub regex, ""

    #dingbats
    regex = /[\u{2702}-\u{27b0}]/
    clean = clean.gsub regex, ""
  end

Results:

结果:

irb> strip_emoji("????????☂❤华み원❤")
=> "华み원"

REGEX = /[^\u{1F600}-\u{1F6FF}\s]/

or

REGEX = /[\u{1F600}-\u{1F6FF}\s]/
REGEX = /[\u{1F600}-\u{1F6FF}]/
REGEX = /[^\u{1F600}-\u{1F6FF}]/

because your original regex seems to indicate you try to find everything that is not an amoji and not a whitespace and I don't know why would you want to do it.

因为您最初的regex似乎表明您试图查找所有不是amoji也不是空格的内容,我不知道您为什么要这样做。

Also:

另外:

  • the emoji are 1F300-1F6FF rather than 1F600-1F6FF; you may want to change that

    表情符号是1F300-1F6FF,而不是1F600-1F6FF;你可能想要改变它。

  • if you want to remove all astral characters (for example you deal with a software that doesn't support all of Unicode), you should use 10000-10FFFF.

    如果您想要删除所有的星体字符(例如,您要处理一个不支持所有Unicode的软件),您应该使用10,000 - 10ffff。

EDIT: You almost certainly want REGEX = /[\u{1F600}-\u{1F6FF}]/ or similar. Your original regex matched everything that is not a whitespace, and not in range 0-\u1F6F. Since spaces are whitespace, and English letters are in range 0-\u1F6F, and Chinese characters are in neither, the regex matched Chinese characters and removed them.

编辑:您几乎肯定想要REGEX = /[\u{1F600}-\u{1F6FF}]/或类似的。您的原始regex匹配了所有非空白、不在0-\u1F6F范围内的内容。由于空格是空格,英文字母在0-\u1F6F范围内,而中文字符在两者都不在范围内,所以regex会匹配并删除它们。

Instead of removing Emoji characters, you can only include alphabets and numbers. A simple tr should do the trick, .tr('^A-Za-z0-9', ''). Of course this will remove all punctuation, but you can always modify the regex to suit your specific condition.

你不能删除表情符号,你只能包括字母和数字。一个简单的tr应该做的诀窍,.tr(“^ A-Za-z0-9“,”)。当然,这将删除所有的标点符号,但是您始终可以修改regex以适应您的特定条件。

This very short Regex covers all Emoji in getemoji.com so far:

这个非常短的Regex涵盖了getemoji.com上所有的表情符号:
