From: Benoit Daloze on 28 Jan 2010 13:05 With ruby 1.9.2dev (2010-01-14 trunk 26319) [x86_64-darwin10.2.0] "strhanziend" It works fine. You need to set encoding with "# encoding: utf-8" at the top of the file. In fact, it will complain if not in 1.9.2 Ruby 1.8.6 is kind of outdated, but at least I think it works with "-Ku". 2010/1/28 Ryan Smith <sunraise2005(a)gmail.com>: > gsub not works for me when replace 'DBCS'(double byte character set) > character, using last version ruby 1.8.6 > > when "strºº×Öend".gsub(/ºº×Ö/,"hanzi"), > output still is: strºº×Öend , but not strhanziend which I want to > get. > > Searched web two whole night with no clue found. > > Anyone can help are much appreciated, need got it work very urgent. > thank you! > -- > Posted via http://www.ruby-forum.com/. > >
From: Ryan Smith on 28 Jan 2010 13:13 I parse a webpage which encoded in gb2312, using Watir to get the context of the page title, and want to replace the 'chinese character' in title with english words. When puts title which watir get, the chinese character displaied as corrupt code there (under windows cmd,code page using cp936, display works normal when change code page to utf-8). But I think cmd's code page just display setting does not related with what I need (replace chinese char). I did not know if string I get by Watir is also in 'gb2312' encoding or something others, the fact is fail happen when convert the string to utf-8 encoding, message is complain the char is invalid. totally no idea what need to do.

Ruby 1.8 isn't outdated. It just doesn't handle multibyte text that well. > > 2010/1/28 Ryan Smith <sunraise2005(a)gmail.com>: Best, -- Marnen Laibow-Koser http://www.marnen.org marnen(a)marnen.org -- Posted via http://www.ruby-forum.com/. |
