这几天频繁在windows和ubuntu下调试代码，字符编码格式不同老是造成很大的困扰，windows下的默认字符编码格式是GBK（gb2312）而在ubuntu下的是utf-8。前天光来回的保存编码格式就费了很大的劲，今天google了下找到了个临时还算是不错的方法。
ubuntu下自带一个字符编码格式调整命令：iconv
ICONV(1) Debian GNU/Linux ICONV(1)
NAME
iconv - Convert encoding of given files from one encoding to another
SYNOPSIS
iconv -f encoding [-t encoding] [inputfile]...
DESCRIPTION
The iconv program converts the encoding of characters in inputfile, or
from the standard input if no filename is specified, from one coded
character set to another. The result is written to standard output
unless otherwise specified by the --output option.
--from-code, -f encoding
Convert characters from encoding.
--to-code, -t encoding
Convert characters to encoding. If not specified the encoding
corresponding to the current locale is used.
--list, -l
List known coded character sets.
-c Omit invalid characters from output.
--output, -o file
Specify output file (instead of stdout).
--silent, -s
Suppress warnings, but not errors.
--verbose
Print progress information.
--help, -?
Give help list.
--usage
Give a short usage message.
--version, -V
Print program version.
ENCODINGS
The values permitted for --from-code and --to-code can be listed by the
iconv --list command, and all combinations of the listed values are
supported. Furthermore the following two suffixes are supported:
//TRANSLIT
When the string "//TRANSLIT" is appended to --to-code,
transliteration is activated. This means that when a character
cannot be represented in the target character set, it can be
approximated through one or several similarly looking
characters.
//IGNORE
When the string "//IGNORE" is appended to --to-code, characters
that cannot be represented in the target character set will be
silently discarded.

通过上面的介绍估计大家就可以很好的理解了。
iconv -f gb2312 -t utf-8 a.txt > b.txt;
就可以将字符编码为gb2312的文件a.txt转换到编码格式为utf-8的b.txt文件。这样就可以在ubuntu下正常的查看了。希望可以帮到大家，自己也留底备用。
