character-encoding

问题 I have a Text object that contains some number of Latin characters that needs to be converted to a unicode escape sequence of the format \u#### with # being hex digits As described here, haskell easily converts strings to escape sequences and vice versa. However, it will only go to the decimal representation. For example, > let s = "Ñ" > s "\209" Is there a way to specify the escape sequence encoding to force it to spit out in the correct format? i.e > let s = encodeUnicode16 "Ñ" > s "\u00d1"

问题 I have a Delphi 7 application. I need to be able to get the default Windows character set for non-unicode programs. I know DEFAULT_CHARSET sets it, but I need to know exactly which charset it is, so that I could compare it to other character sets. Is this possible and how? Thanks! 回答1: GetFontData is calling GetObject and using LogFont.lfCharSet to determine the charset GetObject called with HFONT will fill LogFont Definition here is DEFAULT_CHARSET is set to a value based on the current

问题 According to the gcc manual, the option -fwide-exec-charset specifies the wide character set of wide string and character constants at compile time. But what is the wide character set when converting a multi-byte character to a wide character by calling mbtowc() at run time? The POSIX standard says that the character set of multi-byte characters is determined by the LC_CTYPE category of the current locale, but says nothing about the wide character set. I don't have a C standard at hand now so

问题 I am working on PostgreSQL and getting below error during insert statement execution from batch script(command line). ERROR: invalid byte sequence for encoding "UTF8": 0xeb 0x6e 0x74 I have checked client_encoding by show client_encoding command and it is showing UTF-8.

问题 Reading K&R 1st paragraph page 44 Chapter 2 - The definition of C guarantees that any character in the machine's standard printing set will never be negative, so these characters will always be positive quantities in expressions. Well enough, but when I run the following code #include <stdio.h> int main(void) { printf("%d", '£'); return 0; } I get -93 as the output. I will just cite some of the negative values I get along with the corresponding characters: ÿ = -1 , þ = -2 , ÷ = -9 . I don't

问题 I am testing my controller from Symfony2 with PHPUnit and the class WebTestCase return self::$client->request( 'POST', '/withdraw', array("amount" => 130), array(),array()); $this->assertEquals( "You can withdraw up to £100.00.", $crawler->filter("#error-notification")->text()); But I get this error: Expected: "You can withdraw up to £100.00." Actual: "You can withdraw up to £100.00." The thing is that in the webpage and the source code it looks fine, so I am thinking that maybe PHPUnit is
