ruby1.9开始对字符串编码支持已经比较完善,我们可以直接通过使用String类的实例方法encoding,force_encoding,encode,encode!进行相关的编码操作。 学习记录用。转载自网络,详细看参考链接 encoding ruby1.9中为每个字符串对象增加了encoding信息 1 2 3 1.9.3p392 :001>'我还是不懂'.encoding =>#<Encoding:UTF-8> 1....
force_encoding，强制将一种编码转换为一种编码，用这宗编码来重新解析内容。其实上编码问题在各种语言都存在，这儿虫虫选择了Ruby中三个类方法来作为实例演示，其他语言中也有类似的方法和函数，比如：golang中的golang.org/x/text/encoding/simplifiedchinese包。python中的enode()和decode(),XX_name(XX为编码)方法...

abc.force_encoding("UTF-8") puts abc.encoding.name # >> UTF-8 1. 2. 3. 4. 5. 如上代码所示,我创建字符串时,Ruby 赋予它 US-ASCII 编码。再次说明,我们现在不关心 Ruby 是如何处理这个过程的。重点是我不想用 US-ASCII,而想换成 UTF-8 编码。所以我调用了force_encoding(),告诉 Ruby 这实际...

使用delete（“\0”） 前 ，先处理下编码 用force_encoding("iso-8859-1")，或者再试下其他编码格式。祝你好运。
根据文件注释内容可以发现,当前的可执行文件是RubyGems在安装Cocoapods的时候自动生成的,同时会将当前的执行文件放到系统的环境变量路径中,也即存放到了/usr/local/bin中了,这也就解释了为什么我们通过gem安装cocoapods之后,就立马能够识别pod可执行环境了。

I've also rolled my own fork which replaces the erroring code with string = string.force_encoding("utf-8"), and it's been working just fine. The downside is that folks generally cut out all the non-vCard functionality, such as the iCal stuff, in their forks. And some of them ...
