是否有可能像mcrypt库中的功能mcrypt_list_algorithms().是否有像函数一样的iconv_list_encodings？
有没有什么好的解决方案以良好的方式进行这种音译？
我尝试过使用iconv(),但是非常烦人,而且它的行为并不像人们预期的那样.
//TRANSLIT将尝试替换它可能的东西,将所有不可转换的东西留作"？" //IGNORE不会留下"？" 在文本中,但也不会音译,并且E_NOTICE当找到不可转换的字符时也会引发,所以你必须使用带有@ error suppressor的iconv//IGNORE//TRANSLIT(正如一些人在PHP论坛中建议的)实际上是相同的//IGNORE(在php版本5.3.2和5.3.13上自己尝试过)//TRANSLIT//IGNORE与...相同//TRANSLIT它还使用当前区域设置进行音译.
警告 - 许多文本和代码如下!
这里有些例子:
$text = 'Regular ascii text + ??žš? + äöüß + é???ë? + æø€ + $ + ¶ + @';
echo '<br />original: ' . $text;
echo '<br />regular: ' . iconv("UTF-8", "ASCII//TRANSLIT", $text);
//> regular: Regular ascii text + ????? + ???ss + ?????? + ae?EUR + $ + ? + …我知道我可以使用以下命令在OSX下转换单个文件编码:
iconv -f ISO-8859-1 -t UTF-8 myfilename.xxx > myfilename-utf8.xxx
我必须转换一堆具有特定扩展名的文件,所以我想将文件编码从ISO-8859-1转换为UTF-8,用于文件夹/ mydisk/myfolder中的所有*.ext文件
或许有人知道如何做到这一点的语法
谢谢

我试图将iconv指向一个目录,所有文件都将转换为UTF-8,无论当前编码如何
我正在使用此脚本,但您必须指定要进行的编码.如何让它自动检测当前编码？
dir_iconv.sh
#!/bin/bash
ICONVBIN='/usr/bin/iconv' # path to iconv binary
if [ $# -lt 3 ]
then
echo "$0 dir from_charset to_charset"
exit
fi
for f in $1/*
do
if test -f $f
then
echo -e "\nConverting $f"
/bin/mv $f $f.old
$ICONVBIN -f $2 -t $3 $f.old > $f
else
echo -e "\nSkipping $f - not a regular file";
fi
done

在 Mac OSX 上从源代码编译某些包时，出现以下 iconv 错误：
Undefined symbols for architecture x86_64:
"_iconv", referenced from:
"_iconv_close", referenced from:
"_iconv_open", referenced from:
或者我得到：
Undefined symbols for architecture x86_64:
"_libiconv", referenced from:
"_libiconv_open", referenced from:
"_libiconv_close", referenced from:
为什么会发生这种情况，我该如何解决这种依赖性，或者更一般地说，弄清楚发生了什么以及如何解决它？
我正在尝试在Mac OS X Lion中编译GCC 4.5.1.
我有libiconv的问题.首先,它抱怨的建筑x86_64的未定义的符号,其分别为:_iconv,_iconv_open和_iconv_close.我发现MacPorts版本的libiconv将这些重命名为:_libiconv,_libiconv_open和_libiconv_close.所以我链接到/ usr/lib中的Mac OS本机libiconv而不是/ opt/local/lib中的MacPorts库.
Undefined symbols for architecture x86_64:
"_iconv", referenced from:
_convert_using_iconv in libcpp.a(charset.o)
__nl_find_msg in libintl.a(dcigettext.o)
(maybe you meant: __cpp_destroy_iconv, _cpp_init_iconv )
"_iconv_close", referenced from:
__cpp_destroy_iconv in libcpp.a(charset.o)
__cpp_convert_input in libcpp.a(charset.o)
__nl_free_domain_conv in libintl.a(loadmsgcat.o)
"_iconv_open", referenced from:
_init_iconv_desc in libcpp.a(charset.o)
__nl_init_domain_conv in libintl.a(loadmsgcat.o)
但是,在这之后,我尝试从头开始重建它(清理和所有内容),但后来却抱怨未定义符号的不同点,但这次是_libiconv,_libiconv_open和_libiconv_close.
Undefined symbols for architecture x86_64:
"_libiconv", referenced from:
_identifier_to_locale in libbackend.a(pretty-print.o)
"_libiconv_close", referenced from:
_identifier_to_locale in libbackend.a(pretty-print.o)
"_libiconv_open", referenced from:
_identifier_to_locale in libbackend.a(pretty-print.o)
我有什么想法可以解决这个问题吗？我找到了从MacPorts卸载libiconv的一些解决方案,但我不想这样做,因为我有很多端口取决于它.
我的系统是SUSE Linux Enterprise Server 11.
我正在尝试将数据从utf-8格式转换为iso使用"iconv"
$>file test.utf8
test.utf8: UTF-8 Unicode text, with very long lines
$>
$>file -i test.utf8
test.utf8: text/plain charset=utf-8
$>
$>iconv -f UTF-8 -t ISO-8859-1 test.utf8 > test.iso
iconv: test.utf8:20:105: cannot convert
你能帮我解释一下吗？谢谢.
$string = iconv("UTF-8", "UTF-8//IGNORE", $string);
我认为这段代码会删除无效的UTF-8字符,但它会产生[E_NOTICE] "iconv(): Detected an illegal character in input string".我错过了什么,如何从非法字符中正确地删除字符串？
