Char to UTF code in vbscript

阅读更多关于 Char to UTF code in vbscript

问题 I'd like to create a .properties file to be used in a Java program from a VBScript. I'm going to use some strings in languages that use characters outside the ASCII map. So, I need to replace these characters for its UTF code. This would be \u0061 for a, \u0062 fro b and so on. Is there a way to get the UTF code for a char in VBScript? 回答1: VBScript has the AscW function that returns the Unicode (wide) code of the first character in the specified string. Note that AscW returns the character

SQL doesnt differentiate u and ü although collation is utf8mb4_unicode_ci

阅读更多关于 SQL doesnt differentiate u and ü although collation is utf8mb4_unicode_ci

问题 In a table x , there is a column with the values u and ü . SELECT * FROM x WHERE column='u' . This returns u AND ü , although I am only looking for the u . The table's collation is utf8mb4_unicode_ci . Wherever I read about similar problems, everyone suggests to use this collation because they say that utf8mb4 really covers ALL CHARACTERS. With this collation, all character set and collation problems should be solved. I can insert ü , è , é , à , Chinese characters , etc. When I make a SELECT

UTF Encoding for Chinese CharactersJava

问题 I am receiving a String via an object from an axis webservice. Because I'm not getting the string I expected, I did a check by converting the string into bytes and I get C3A4C2 BDC2A0 C3A5C2 A5C2BD C3A5C2 90C297 in hexa, when I'm expecting E4BDA0 E5A5BD E59097 which is actually 你好吗 in UTF-8. Any ideas what might be causing 你好吗 to become C3A4C2 BDC2A0 C3A5C2 A5C2BD C3A5C2 90C297? I did a Google search but all I got was a chinese website describing a problem that happens in python. Any insights

Is there a field in which PDF files specify their encoding?

阅读更多关于 Is there a field in which PDF files specify their encoding?

问题 I understand that it is impossible to determine the character encoding of any stringform data just by looking at the data. This is not my question. My question is: Is there a field in a PDF file where, by convention, the encoding scheme is specified (e.g.: UTF-8)? This would be something roughly analogous to <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> in HTML. Thank you very much in advance, Blz 回答1: A quick look at the PDF specification seems to suggest

阅读更多关于 What most correct way to set the encoding in C++?

问题 How it is best of all to set the encoding in C++? I got used to working with Unicode (and wchar_t , wstring , wcin , wcout and L" ... "). I also save source in UTF-8. At the moment I use MinGW (Windows 7) and run my program in Windows console (cmd.exe), but sometimes I can use gcc on GNU\Linux and run promgram in Linux console with UTF-8 encoding. At all times I want to compile my source on Windows and on Linux and I want that all Unicode symbols were correctly inputed and outputed. When I

is PHP str_word_count() multibyte safe?

阅读更多关于 is PHP str_word_count() multibyte safe?

I want to use str_word_count() on a UTF-8 string. Is this safe in PHP? It seems to me that it should be (especially considering that there is no mb_str_word_count() ). But on php.net there are a lot of people muddying the water by presenting their own 'multibyte compatible' versions of the function . So I guess I want to know... Given that str_word_count simply counts all character sequences in delimited by " " (space), it should be safe on multibyte strings, even though its not necessarily aware of the character sequences, right? Are there any equivalent 'space' characters in UTF-8, which are

How many characters can be mapped with Unicode?

阅读更多关于 How many characters can be mapped with Unicode?

I am asking for the count of all the possible valid combinations in Unicode with explanation. I know a char can be encoded as 1,2,3 or 4 bytes. I also don't understand why continuation bytes have restrictions even though starting byte of that char clears how long it should be. dan04 I am asking for the count of all the possible valid combinations in Unicode with explanation. 1,111,998 : 17 planes × 65,536 characters per plane - 2048 surrogates - 66 noncharacters Note that UTF-8 and UTF-32 could theoretically encode much more than 17 planes, but the range is restricted based on the limitations
