unicode-string

问题 I would like to print that kind of character, but I dont get it, I thought c# supports unicode. The way I solved it: label3.Text = "\u1F6B5"; This is not the only symbol ,which does not work. Thank you. 回答1: label3.Text = "\u1F6B5"; The \u escape takes only 4 hex digits, you are trying to use 5. So you end up with a string that contains two characters, '\u1F6B' and '5'. Looks like "Ὣ5", not what you want. Using codepoints from the upper bit planes (codes >= 0x10000) require a capital U to get

问题 I'm writing a Delphi package with RAD Studio XE7. I recently faced a strange access violation, and I cannot figure out why it happened. The context was that I was trying to maintain a list of font names. So I declared the following type: ICustomFontList = TList<UnicodeString>; Inside one of my classes, I declared a variable as follow: m_pCustomFontList: ICustomFontList; Then, in the constructor, I tried to instantiate this variable like that: m_pCustomFontList := ICustomFontList.Create; I

问题 An device encodes a string "🤛🏽" as "\uD83E\uDD1B\uD83C\uDFFD" . The hexadecimal numbers represented in this string are from the UTF-16 hex encoding of the character. The Unicode code point U+1F91B, U+1F3FD gets its numbers from the UTF-32 hex encoding. Taking this later one, in Swift we can do a literal like this "\u{1F91B}\u{1F3FD}" and we will get the character "🤛🏽" as expected. How can I convert from the UTF-16 hex string "\uD83E\uDD1B\uD83C\uDFFD" to get the "🤛🏽"? I've tried taking the

问题 I am doing some scraping work with Python 3.6 and retrieved some URLs in strings following this format: someURL = 'http:\u002F\u002Fsomewebsite.com\u002Fsomefile.jpg' I have been trying to convert the Unicode backslash (\u002F) in those strings in order to use the URLs (using regex methods, encode() on the strings, etc.), to no avail. The string still keeps the Unicode backslash and, if I pass it on to Requests' get(), for example, I am greeted by the following error message: InvalidURL:

问题 I'm trying to port a Python 3.5 project from PC to Android QPython3 but for the line:- if ch = in u'\x00\xe0': ch = getwch() I'm getting this when I run it:- if ch = in u'\x00\xe0': ^ SyntaxError: invalid syntax I thought QPython3 was supposed to run all 3.x scripts and the Unicode 'u' prefix isn't a new addition so what can the problem be? Are hex numbers in strings treated differently? 回答1: To answer my own question, after much fiddling about I got it to work using:- if ch in bytes([0x00,

问题 Issues: Using ls in GIT shows all unicode in filenames as '?' (i.e. ???.mp3). When using git add -A the following error is returned: "fatal: unable to stat 'example/???.mp3': no such file or directory" Is there a solution to this? Thanks. 回答1: Msysgit doesn't have support for non-ASCII characters in filenames. See its issue 80 for details. Consider using Cygwin's git package instead, which does have full UTF-8 support. 回答2: As of MSysGit 1.7.10 (the latest version at this time), Unicode is

问题 I need to change the first letter of every line in a file to uppercase, e.g. the bear ate the fish. the river was too fast. Would become: The bear ate the fish. The river was too fast.

问题 I have this code, which convert UTF-8 string to Unicode: #include <unicode/unistr.h> //included other header files int main(int argc, char** argv) { std::string s("some string"); // convert std::string to ICU's UnicodeString UnicodeString ucs = UnicodeString::fromUTF8(StringPiece(s.c_str())); // convert UnicodeString to std::wstring std::wstring ws; for (int i = 0; i < ucs.length(); ++i) ws += static_cast<wchar_t>(ucs[i]); std::wcout << ws; } I can not understand how to convert this

问题 I have a string of the format: "aaa\\u2022bbb\\u2014ccc" I'd like to display the two special charactes, but to be able to do that, I have to first convert the string to this format: "aaa\u2022bbb\u2014ccc" I've tried writing this, but it gives a compilation error: String encodedInput = input.replace("\\u", "\u"); This has got to be something straightforward, but I just cannot get it. Any ideas? 回答1: Unfortunately I do not know of a sort of eval. String s = "aaa\\u2022bbb\\u2014ccc";
