将不间断空格转换为Ruby中的空格 [英] Convert non-breaking spaces to spaces in Ruby

问题描述

在某些情况下，来自html文本区域或输入的用户输入的数据有时会以\u00a0(不间断空格)发送，而不是编码为utf-8 json的空格.

I have cases where user-entered data from an html textarea or input is sometimes sent with \u00a0 (non-breaking spaces) instead of spaces when encoded as utf-8 json.

我相信这是Firefox中的错误，因为我知道用户并不是故意在不间断的空格中放置空格而不是空格.

I believe that to be a bug in Firefox, as I know that the user isn't intentionally putting in non-breaking spaces instead of spaces.

Ruby中还有两个错误，其中一个可以用来与另一个进行抗争.

There are also two bugs in Ruby, one of which can be used to combat the other.

由于任何原因\s与\u00a0不匹配.

For whatever reason \s doesn't match \u00a0.

但是[^[:print:]]，这两个绝对不匹配)和\xC2\xA0都将匹配，但是我认为这是处理问题的不理想方法.

However [^[:print:]], which definitely should not match) and \xC2\xA0 both will match, but I consider those to be less-than-ideal ways to deal with the issue.

还有其他解决此问题的建议吗?

Are there other recommendations for getting around this issue?
