保证你要转换的字符串编码为UTF8,如果不是,请iconv cnStr成utf8

$cnStr = "中"; //utf8的中文

//unicode
$code = unpack("H6codes", $cnStr);

//汉字
$cnStr = pack("H6", $code['codes']);

恩, pack/unpack很强大,, 和c语言交换数据, 二进制方式的序列化,操作二进制文件.. etc…

附上format参数的说明:

a 	NUL-padded string, 即"\0"作为"空字符"的表示形式
A 	SPACE-padded string, 空格作为"空字符"的表示形式
h 	Hex string, low nibble first,升序位顺序
H 	Hex string, high nibble first,降序位顺序
c 	signed char, 有符号单字节
C 	unsigned char, 无符号单字节
s 	signed short (always 16 bit, machine byte order)
S 	unsigned short (always 16 bit, machine byte order)
n 	unsigned short (always 16 bit, big endian byte order)
v 	unsigned short (always 16 bit, little endian byte order)
i 	signed integer (machine dependent size and byte order)
I 	unsigned integer (machine dependent size and byte order)
l 	signed long (always 32 bit, machine byte order)
L 	unsigned long (always 32 bit, machine byte order)
N 	unsigned long (always 32 bit, big endian byte order)
V 	unsigned long (always 32 bit, little endian byte order)
f 	float (machine dependent size and representation)
d 	double (machine dependent size and representation)
x 	NUL byte, 实际使用的时候作为跳过多少字节用,很有用
X 	Back up one byte, 后退1字节
@ 	NUL-fill to absolute position,实际使用的时候作为从开头跳到某字节用.

set langmenu=zh_CN.utf8
set fileencodings=utf-8,cp936,big5,latin1
set ambiwidth=double
let $LANG=’en’

或者也可以:

set encoding=utf-8
set fileencodings=utf-8,chinese,latin-1
if has(“win32″)
set fileencoding=chinese
else
set fileencoding=utf-8
endif
“解决菜单乱码
source $VIMRUNTIME/delmenu.vim
source $VIMRUNTIME/menu.vim
“解决consle输出乱码
language messages zh_CN.utf-8

下面的方法经过我测试，是可以完美解决的，第一种没有经过测试
