multibyte

问题 I'm once again messing around with the java natve interface, and I've runned into another interesting problem. I'm sending a filepath to c via jni and then doing some I/O. So the most common chars I have troubles with is 'äåö' . Here is a short demo of a program with the exact same problem: Java: public class java { private static native void printBytes(String text); static{ System.loadLibrary("dll"); } public static void main(String[] args){ printBytes("C:/Users/ä-å-ö/Documents/Bla.txt"); }

问题 I have some text to be printed in Tamil. How can I get it printed in Tamil on Java console. I'm testing a piece of code and for debugging I require to see the text being printed. public static void main(String[] args) { String str = "வீடிவீடிவீடிவீடிவீடி"; System.out.println("String is : "+str); } Shows output in java console as String is : ????????????? 回答1: If you use Eclipse Ide change bottom configurations and try. Window > Preferences > General > Content Types, set UTF-8 as the default

问题 I am currently working on a program that extract text messages from a third party program, so I dont have to enter tooltip text manually in my excel sheets. I am using dll injection for this and have already successfully hooked the microsoft's textoutw function. The program also gives me the messages I want. So the hook was successful. Now, I want to put some "cloths" (a GUI) on my program and have decided to go with Qt. So I designed a GUI and have put my dll engine into the GUI. After I

问题 If I write: rename('php109.tmp','test.jpg'); then it's fine and working. but if I change it into: rename('php109.tmp','中文.jpg'); it'll report "No such file or directory...". But if the multi-byte characters can be written into database then can be read out, then why it fails when it is renamed ? 回答1: File systems do not necessarily use UTF-8. For instance, this is what Wikipedia says about NTFS: NTFS allows any sequence of 16-bit values for name encoding (file names, stream names, index names

问题 I'm looking for a multi-byte function to replace preg_match_all() . I need one that will give me an array of matched strings, like the $matches argument from preg_match() . The function mb_ereg_match() doesn't seem to do it -- it only gives me a boolean indicating if there were any matches. Looking at the mb_* functions page, I don't offhand see anythng that replaces the functionality of preg_match() . What do I use? Edit I'm an idiot. I originally posted this question asking for a

问题 I have a field scraped from a utf-8 page: "O’Reilly" And saved in a yml file: :name: "O\xE2\x80\x99Reilly" (xE2x80x99 is the correct UTF-8 representation of this apostrophe) However when I load the value into a hash and yield it to a page tagged as utf-8, I get: OâReilly I looked up the character â, which is encoded in UTF-16 as x00E2, and the characters x80 and x89 were invisible but present after the â when I pasted the string. I assume this means my app is outputting three UTF-16

问题 This question already has answers here : Should I use multi-byte overloading (mbstring.func_overload)? (2 answers) Closed 6 years ago . I want to conform my site's string handling to support other languages per UTF-8. It seems that the best way to do this is to forsake all the standard string functions. So I have two options, I can set the mbstring.func_overload option in php.ini or I can go back over my code and just replace all the functions with mb_* . I would assume that the second option

问题 How do I get the byte size of a multibyte-character string in Visual C? Is there a function or do I have to count the characters myself? Or, more general, how do I get the right byte size of a TCHAR string? Solution: _tcslen(_T("TCHAR string")) * sizeof(TCHAR) EDIT: I was talking about null-terminated strings only. 回答1: According to MSDN, _tcslen corresponds to strlen when _MBCS is defined. strlen will return the number of bytes in the string. If you use _tcsclen that corresponds to _mbslen

问题 The explode() function has a correlating multibyte-safe function in mb_split() . I don't see a correlating function for implode() . Does this imply that implode is already safe for multibyte strings? 回答1: As long as your delimiter and the strings in the array contain only well-formed multibyte sequences there should not be any issues. implode basically is a fancy concatenation operator and I couldn't imagine a scenario where concatenation is not multibyte safe ;) 来源： https://stackoverflow.com

问题 Will it make any difference or impact on my result, if I use substr() instead of mb_substr() function? As my server does not have support for mb_ functions, I have to replace it with substr() 回答1: It will impact your script if you work with multi-byte text that you substring from. If this is the case, I higly recommend enabling mb_* functions in your php.ini or do this ini_set("mbstring.func_overload", 2); 回答2: string substr ( string $string , int $start [, int $length ] ) Returns the portion
