[C ++] zlatlcv: Auxiliary library for ATL String Conversion. Can easily convert the UTF-8 string to a string such as TCHAR, zlatlcvtchar

Author: zyl910

 

Today, UTF-8 strings are increasingly used. But in VC, you cannot directly process the UTF-8 string, you have to specifically write UTF-8 and narrow string, wide string, TCHAR String Conversion code. It is not only time-consuming and laborious, but it is easy to cause memory leakage if you do not pay attention to it. So I want to write a library to solve the problem of UTF-8 string encoding.

Feature --
TCHAR is supported and the character set configuration of the project can be switched at any time.
Compatible with 32-bit (x86) and 64-bit (x64) Windows environments.
Compatible with VC2005 and later versions of VC.

I. Design Ideas

The String Conversion macro in ATL is very convenient to use, so I plan to refer to it and make a set of String Conversion macros.

Convert macro naming rules --

C <SourceType> 2 [C] <DestinationType> [EX]

<SourceType> and <DestinationType>: string type. It can be A (char), W (wchar_t), T (TCHAR), U8 (UTF-8 ).
[C]: whether it is a constant.
[EX]: whether it is an enhanced version. Whether a template parameter such as t_nBufferLength exists.

For example, commonly used conversion macros include --

CU82A: converts a UTF-8 string into a narrow string.
CA2U8: converts a narrow string into a UTF-8 string.
CU82W: converts a UTF-8 string to a wide string.
CW2U8: converts a wide string into a UTF-8 string.
CU82T: Convert the UTF-8 string to a TCHAR string.
CT2U8: convert a TCHAR string to a UTF-8 string.

Ii. Sample Code

Sample Code --

# Include <stdio. h> # include <locale. h> # include <tchar. h> # include "zlatlcv. h "//" Welcome ": English, Traditional Chinese, Japanese, Korean. const char * psa = "A_Welcome _ うこそ _ 환 영. ";//! <UTF-8 string (Auto. file used UTF-8 encoding ). const wchar_t * psw = L "W_Welcome _ \ u6B61 \ u8FCE _ \ u3088 \ u3046 \ u3053 \ u305D _ \ uD658 \ uC601 .";//! <Wide char string.int _ tmain (int argc, _ TCHAR * argv []) {// init. setlocale (LC_ALL, ""); // use the default locale. // title. _ tprintf (_ T ("zlatlcv v1.0 (% dbit) \ n"), (int) (8 * sizeof (int *))); _ tprintf (_ T ("sizeof (wchar_t): % d \ n"), (int) (sizeof (wchar_t ))); _ tprintf (_ T ("sizeof (TCHAR): % d \ n"), (int) (sizeof (TCHAR ))); _ tprintf (_ T ("\ n"); // printf. fflush (stdout); printf ("printf A: \ t % s \ n", psa); printf ("printf W: \ t % ls \ n", psw ); printf ("\ n"); // UTF-8 to string (UTF-8 to various strings ). // CA2AZ psaa (psa, CP_UTF8, 0); CU82A psaa (psa); CU82W psaw (psa); printf ("printf A from UTF-8: \ t % s \ n ", psaa); printf ("printf W from UTF-8: \ t % ls \ n", psaw); printf ("\ n "); // string to UTF-8 (various string to UTF-8 ). CA2U8 psau8 (psaa); CW2U8 pswu8 (psaw); fflush (stdout); printf ("printf UTF-8 from A: \ t % s \ n", psau8 ); printf ("printf UTF-8 from W: \ t % s \ n", pswu8); // _ tprintf. CA2CT psat (psa); CW2CT pswt (psw); CU82T psu8t (psa); fflush (stdout); _ tprintf (_ T ("_ tprintf: \ t % s \ n "), psat); _ tprintf (_ T (" _ tprintf W: \ t % s \ n "), pswt ); _ tprintf (_ T ("_ tprintf U8: \ t % s \ n"), psu8t); return 0 ;}
