对于Ruby 1.8.6，您可以使用Ruby Iconv是标准库的一部分：

Iconv文档

根据这个有用的文章，似乎您可以至少从字符串中清除不需要的win-1252字符，如下所示：

  ic = Iconv.new（'UTF-8 // IGNORE'，'UTF-8'）
 valid_string = ic.iconv untrusted_string +''）[0 ..- 2] 
 

然后可能会尝试进行完全转换像这样：

  ic = Iconv.new（'UTF-8'，'W INDOWS-1252'）
 valid_string = ic.iconv（untrusted_string +''）[0 ..- 2] 
 

I'm migrating some data from MS Access 2003 to MySQL 5.0 using Ruby 1.8.6 on Windows XP (writing a Rake task to do this).

Turns out the Windows string data is encoded as windows-1252 and Rails and MySQL are both assuming utf-8 input so some of the characters, such as apostrophes, are getting mangled. They wind up as "a"s with an accent over them and stuff like that.

Does anyone know of a tool, library, system, methodology, ritual, spell, or incantation to convert a windows-1252 string to utf-8?

For Ruby 1.8.6, it appears you can use Ruby Iconv, part of the standard library:

Iconv documentation

According this helpful article, it appears you can at least purge unwanted win-1252 characters from your string like so:

ic = Iconv.new('UTF-8//IGNORE', 'UTF-8')
valid_string = ic.iconv(untrusted_string + ' ')[0..-2]

One might then attempt to do a full conversion like so:

ic = Iconv.new('UTF-8', 'WINDOWS-1252')
valid_string = ic.iconv(untrusted_string + ' ')[0..-2]
