问题 int main() { wcout << L"Русский текст" << endl; wprintf(L"Русский текст\n"); return 0; } This simple program doesn't print anything to the Console window (not even new lines). VC++ 2010 Console Application project. What is wrong? 回答1: According to links pointed to in this blog you need to change the font of the console and also this line: _setmode(_fileno(stdout), _O_U16TEXT); 来源： https://stackoverflow.com/questions/20729870/cannot-print-non-english-text-to-the-console-window

Asian language PDF display issue in Crystal Reports for VS2008

由 与世无争的帅哥 提交于 2020-02-05 07:38:04
问题 Here is the context: we use Crystal Reports for Visual Studio 2008 in a ASP.Net application to generate reports which may contain East Asian characters (Chinese, Japanese) in the text entered by the users. The reports are correctly generated on a Windows Server 2003 and incorrectly on Windows Server 2008. When we first had this issue, we found that we needed to: install "East Asian language support" on the server use a Unicode font in CR: Arial Unicode MS install this font on the server With

Unicode字符串

字符串还有一个编码问题。 因为计算机只能处理数字，如果要处理文本，就必须先把文本转换为数字才能处理。最早的计算机在设计时采用8个比特（bit）作为一个字节（byte），所以，一个字节能表示的最大的整数就是255（二进制11111111=十进制255），0 - 255被用来表示大小写英文字母、数字和一些符号，这个编码表被称为ASCII编码，比如大写字母 A 的编码是65，小写字母 z 的编码是122。 如果要表示中文，显然一个字节是不够的，至少需要两个字节，而且还不能和ASCII编码冲突，所以，中国制定了GB2312编码，用来把中文编进去。 类似的，日文和韩文等其他语言也有这个问题。为了统一所有文字的编码，Unicode应运而生。Unicode把所有语言都统一到一套编码里，这样就不会再有乱码问题了。 Unicode通常用两个字节表示一个字符，原有的英文编码从单字节变成双字节，只需要把高字节全部填为0就可以。 因为Python的诞生比Unicode标准发布的时间还要早，所以最早的Python只支持ASCII编码，普通的字符串'ABC'在Python内部都是ASCII编码的。 Python在后来添加了对Unicode的支持，以Unicode表示的字符串用u'...'表示，其中的转义依然起作用，比如： print(u'中文') 运行结果 中文 转义： u'中文\n日文\n韩文' 多行： u

代码点 Unicode标准 的本意很简单：希望给世界上每一种文字系统的每一个字符，都分配一个唯一的整数，这些整数叫做代码点（Code Points）。 代码空间 所有的代码点构成一个代码空间（Code Space） ，根据Unicode定义，总共有 1,114,112 个代码点，编号从0x0到0x10FFFF。换句话说，如果每个代码点都能够代表一个有效字符的话，Unicode标准最多能够编码1,114,112，也就是大概110多万个字符。最新的Unicode标准（7.0）已经给超过11万个字符分配了代码点。 代码平面 Unicode标准把代码点分成了17个代码平面（Code Plane），编号为#0到#16。每个代码平面包含65,536（2^16）个代码点（17*65,536=1,114,112）。其中，Plane#0叫做基本多语言平面（Basic Multilingual Plane，BMP），其余平面叫做补充平面（Supplementary Planes）。Unicode7.0只使用了17个平面中的6个，并且给这6个平面起了名字，如下图所示： 下面是这些平面的名字和用途： BMP（Basic Multilingual Plane） 大部分常用的字符都坐落在这个平面内，比如ASCII字符，汉字等。 SMP（Supplementary Multilingual Plane）

Search for unicode text inside Windows XP

由 假如想象 提交于 2020-02-04 08:08:33
问题 Is there a way of searching for unicode characters inside a text file under Windows XP? For example suppose I wish to find text documents with the euro symbol. Although the standard XP search allows me to search for the euro symbol it does not produce any matches when I know they should be at least a few. Wingrep has the same issue. Is there any simple software/setting the I have missed? 回答1: The input encoding of the search field (in Windows XP, UTF-16) may not match the encoding of the text

Insert rows with Unicode characters using BCP

由 一个人想着一个人 提交于 2020-02-03 05:35:25
问题 I'm using BCP to bulk upload data from a CSV file to SQL Azure (because BULK INSERT is not supported). This command runs and uploads the rows: bcp [resource].dbo.TableName in C:\data.csv -t "," -r "0x0a" -c -U bcpuser@resource -S tcp:resource.database.windows.net But data.csv is UTF8 encoded and contains non-ASCII strings. These get corrupted. I've tried changing the -c option to -w: bcp [resource].dbo.TableName in C:\data.csv -t "," -r "0x0a" -w -U bcpuser@resource -S tcp:resource.database
