这很简单:如何删除特殊字符的ruby字符串?这是角色: http://www.fileformat.info/info/unicode/char/2028/index.htm
这是字符串,句点和结尾引号之间有两个特殊字符:
"Each of the levels requires logic, skill, and brute force to crush the enemy.
"
我没试过这个:
string.gsub!(/[\x00-\x1F\x7F]/, '')
和gsub("/\n/", "")
我正在使用ruby 1.9.3p125

String#gsub
会有效,但比String#tr
irb> s ="Hello,\u2028 World; here's some ctrl [\1\2\3\4\5\6] chars"
=> "Hello,\u2028 World; here's some ctrl [\u0001\u0002\u0003\u0004\u0005\u0006] chars"
irb> s.tr("\u0000-\u001f\u007f\u2028",'')
=> "Hello, World; here's some ctrl [] chars"
require 'benchmark'
Benchmark.bm {|x|
x.report('tr') { 1_000_000.times{ s.tr("\u0000-\u001f\u007f\u2028",'') } }
x.report('gsub') { 1_000_000.times{ s.gsub(/[\0-\x1f\x7f\u2028]/,'') } }
}
user system total real
tr 1.440000 0.000000 1.440000 ( 1.448090)
gsub 4.110000 0.000000 4.110000 ( 4.127100)
