Multibytetowidechar逻辑问题 [英] Multibytetowidechar logic problem

问题描述

使用

以下方法将一些ansi希伯来字符串转换为unicode字符串：





nSize = MultiByteToWideChar（nlanguageCodePage，0，chAnsiBuff，-1，NULL，0）;



MultiByteToWideChar（nlanguageCodePage，0，chAnsiBuff，-1，chUniocodeBuff，512）; < br $> b $ b



我有希伯来语 - （Windows代码页1255）所以我会得到1255 ....如果ansi中有任何垃圾字符它会消除unicode中的相关性吗？



这究竟是做什么的（即如果我将指定希伯来语仍将其转换为第一个参数将会执行）



请让我知道为什么它不工作



我尝试过：

iam converting some ansi hebrew string to unicode string by using
following method:


nSize = MultiByteToWideChar(nlanguageCodePage, 0, chAnsiBuff, -1, NULL, 0);

MultiByteToWideChar(nlanguageCodePage, 0, chAnsiBuff, -1, chUniocodeBuff, 512);


iam having hebrew - ( windows code page 1255) so i will get 1255 ....if any junk characters are there in ansi it will dispalay correclty in unicode ?

what exactly this will do ( i.e first parameter will do if i willspecify hebrew still its converting proeprly)

please let me know the why its not working

What I have tried:

//CONVERTING TO UNICODE
nSize = MultiByteToWideChar(nlanguageCodePage, 0, chAnsiBuff, -1, NULL, 0);
MultiByteToWideChar(nlanguageCodePage, 0, chAnsiBuff, -1, chUniocodeBuff, 512);

// bom at starting
if (nBOM == 0) { arcOut.Write(&bom, 2); }
arcOut.WriteString(chUniocodeBuff);

推荐答案

该函数用于转换多字节字符串进入宽字符字符串。阅读 MultiByteToWideChar 功能的文档总是一个好主意。



但是当输入 ANSI 时，你最好阅读如何：在各种字符串类型之间进行转换以了解不同的字符串类型。简短：ANSI-char是单字节char，但Multibyte和wide char最多可以是4个字节。因此，请注意使用sizeof-operator和一些字符串长度函数时的区别。转换之前一定要检查尺寸！始终; - ）

The function is for converting Multibyte string into wide char strings. Reading the documentation of the MultiByteToWideChar function is always a good idea.

But when your input is ANSI you better read the How to: Convert Between Various String Types to understand the different string types. A short: a ANSI-char is a single byte char, but the Multibyte and wide char can be up to four bytes. So be aware of the difference when using the sizeof-operator and some string length functions. Always check sizes before converting!!! Always ;-)
