问题 How would one convert -lrb-300-rrb-┬á922-6590 to -lrb-300-rrb- 922-6590 in java? Have tried the following: t.lemma = lemma.replaceAll("\\p{C}", " "); t.lemma = lemma.replaceAll("[\u0000-\u001f]", " "); Am probably missing something conceptual. Will appreciate any pointers to the solution. Thank you 回答1: Try the next: str = str.replaceAll("[^\\p{ASCII}]", " "); By the way, \p{ASCII} is all ASCII: [\x00-\x7F] . In ahother hand, you need to use a constant of Pattern for avoid recompiled the

Handling grapheme clusters in Dart

℡╲_俬逩灬. 提交于 2021-02-07 07:20:32
问题 From what I can tell Dart does not have support for grapheme clusters, though there is talk of supporting it: Dart Strings should support Unicode grapheme cluster operations #34 Minimal Unicode grapheme cluster support #49 Until it is implemented, what are my options for iterating through grapheme clusters? For example, if I have a string like this: String family = '\u{1F468}\u{200D}\u{1F469}\u{200D}\u{1F467}'; // 👨‍👩‍👧 String myString = 'Let me introduce my $family to you.'; and there is a

Defining the character encoding of a JavaScript source file

情到浓时终转凉″ 提交于 2021-02-07 04:45:09
问题 I would like to print a status message to my German users, which contains umlauts (ä/ü/ö). I also would like them be in the source file rather than having to download and parse some extra file just for the messages. However, I can't seem to find a way to define the encoding of a JS source file. Is there something like HTML's http-equiv ? Or should I define the encoding in the HTTP header? When I simply encode the file in UTF-8 an serve it, IE displays garbage. 回答1: Sending the encoding in the

Unicode string display on Django template

问题 I am using django v1.5.*, I am going to render the a variable named "foobar" which is a json obj and including unicode string. def home( request ): import json foo = {"name": u"赞我们一下"} bar = json.dumps( foo ) return render_to_response( 'myapp/home.html', { "foobar": bar, }, context_instance=RequestContext(request) ) And in my template, I encode the json obj in javascript and then append to the div, it can display the expected string: foobar=JSON.encode('{{foobar|safe}}'); $("#foobar").html

Is there a way to check if a string in JS is one single emoji?

倖福魔咒の 提交于 2021-02-06 09:48:27
问题 The question is simple: I have a string str , how do I check if str is one single emoji, and nothing else? Additionally I would prefer not using another library. Match "🍎" , "⛹🏿‍♂️" , "3️⃣" but not "🍓a" , "𝕒" , "🍌🍀" I'm having trouble finding a solution but here are some things I've tried so far: Attempted Solution 1 - Play around lengths and ... operator I learned that emojis occupy more than one byte, some even occupy 4 bytes, or more... and we can measure that via the string's length

Java regex: why numbers [0-9], comma etc. is not an unicode?

血红的双手。 提交于 2021-02-05 12:28:04
问题 class Test { public static void main (String[] args) { String regex = "\\p{L}"; System.out.println("0".matches(regex)); } } The code above prints false, but I was expecting true because isn't ASCII a subset of unicode ? "0" is part of ASCII, so I think it should also belongs to a unicode letter. Also, comma, period etc prints "false" true, while "a" will print true. 回答1: It is because \\p{L} matches a Unicode letter and you're matching a digit. You can use: [\\p{L}\\p{Nd}.,] to match a

Missing presentation forms (glyphs) of some arabic characters in Unicode

时光怂恿深爱的人放手 提交于 2021-02-05 11:14:08
问题 I am working on a code that generates PDF containing arabic texts. For each character, I am choosing the correct glyph in the presentation forms to display the text correctly. This works fine but Unicode doesn't contain presentation form of all arabic characters. For example \u067D ARABIC LETTER TEH WITH THREE DOTS ABOVE DOWNWARDS ٽ. There is no presentation form of this character even though the character has medial form, as can be seen in this string: لٽط What is the reason that

Print UTF-8 multibyte character in C

问题 I wrote this code to print a UTF-8 multibyte string. But it does not print properly. Note: I am doing it in a Linux system. #include <stdio.h> #include <locale.h> int main() { char *locale = setlocale(LC_ALL, ""); printf("\n locale =%s\n", locale); printf("test\n \x263a\x263b Hello from C\n", locale); return 0; } 回答1: Use \u instead of \x : #include <stdio.h> #include <locale.h> int main() { char *locale = setlocale(LC_ALL, ""); printf("\n locale =%s\n", locale); printf("test\n \u263a\u263b
