在 Solaris 8 中,看起来iconv*()
系列函数已损坏,仅支持单字节字符集和UTF-8
之间的转换,可以使用此代码进行验证例如:
#include <stdio.h>
#include <errno.h>
#include <iconv.h>
#if defined(__sun) && defined(__SVR4)
#define CP1251 "ansi-1251"
#define ISO_8859_5 "ISO8859-5"
#else
#define CP1251 "CP1251"
#define ISO_8859_5 "ISO-8859-5"
#endif
void iconv_open_debug(const char *, const char *);
int main() {
iconv_open_debug(CP1251, CP1251);
iconv_open_debug(CP1251, ISO_8859_5);
iconv_open_debug(CP1251, "KOI8-R");
iconv_open_debug(CP1251, "UTF-8");
iconv_open_debug(CP1251, "WCHAR_T");
iconv_open_debug(ISO_8859_5, CP1251);
iconv_open_debug(ISO_8859_5, ISO_8859_5);
iconv_open_debug(ISO_8859_5, "KOI8-R");
iconv_open_debug(ISO_8859_5, "UTF-8");
iconv_open_debug(ISO_8859_5, "WCHAR_T");
iconv_open_debug("KOI8-R", CP1251);
iconv_open_debug("KOI8-R", ISO_8859_5);
iconv_open_debug("KOI8-R", "KOI8-R");
iconv_open_debug("KOI8-R", "UTF-8");
iconv_open_debug("KOI8-R", "WCHAR_T");
iconv_open_debug("UTF-8", CP1251);
iconv_open_debug("UTF-8", ISO_8859_5);
iconv_open_debug("UTF-8", "KOI8-R");
iconv_open_debug("UTF-8", "UTF-8");
iconv_open_debug("UTF-8", "WCHAR_T");
iconv_open_debug("WCHAR_T", CP1251);
iconv_open_debug("WCHAR_T", ISO_8859_5);
iconv_open_debug("WCHAR_T", "KOI8-R");
iconv_open_debug("WCHAR_T", "UTF-8");
iconv_open_debug("WCHAR_T", "WCHAR_T");
return 0;
}
void iconv_open_debug(const char *from, const char *to) {
errno = 0;
if (iconv_open(to, from) == (iconv_t) -1) {
fprintf(stderr, "iconv_open(\"%s\", \"%s\") FAIL: errno = %d\n", to, from, errno);
perror("iconv_open()");
} else {
fprintf(stdout, "iconv_open(\"%s\", \"%s\") PASS\n", to, from);
}
}
仅打印
iconv_open("UTF-8", "ansi-1251") PASS
iconv_open("UTF-8", "ISO8859-5") PASS
iconv_open("UTF-8", "KOI8-R") PASS
iconv_open("ansi-1251", "UTF-8") PASS
iconv_open("ISO8859-5", "UTF-8") PASS
iconv_open("KOI8-R", "UTF-8") PASS
到stdout并返回其他对的EINVAL
。请注意,甚至不支持转换为相同的字符集(例如UTF-8 - > UTF-8)。
iconv.h
的限制的文档吗?wchar_t*
转换为单字节或多字节字符串,而不依赖于 GNU libiconv
? wcstombs()
将正常,除非它依赖于当前语言环境的字符集,而我希望使用特定字符集将宽字符串转换为常规字符串,可能与默认字符串不同。答案 0 :(得分:0)
正在运行sdtconvtool
表示支持大多数旧版代码页。
在使用truss -u libc::iconv_open
重新运行相同的实用程序后,我了解到从一个单字节编码到另一个单字节编码的转换分两步完成,中间转换为UTF-8
。< / p>
说到从"WCHAR_T"
转换,iconv(3)
也支持它,但"UCS-4"
应该用作源字符集名称,因为sizeof(wchar_t)
在Solaris上是4(对于这两者都是如此) x86和SPARC)。
