For example, it is a situation such as the following. 64 | 65 | - A Web application written in UTF-8 using a database saved in EUC-JP 66 | - Exchanging data files(csv,tsv,..) between different systems 67 | 68 | In Ruby, You can convert a character code using `String#encode`, but some characters cannot. `Encoding::UndefinedConversionError` raises when a character is undefined in the destination encoding. But `String#encode` has options. You can specify `:undef => :replace` then replace the undefined characters with the replacement character. 69 | 70 | `Wavedash` is similar to `String#encode` with `:undef => :replace`, but it does more aggressive character conversion. 71 | 72 | Despite some characters have resembling shape, character code point is different each other. For example, when you convert characters to EUCJP-MS from UTF-8, can convert "～" (FULLWIDTH TILDE U+FF5E) but cannot convert "〜" (WAVE DASH U+301C). The opposite will occur when you convert to EUC-JP. 73 | 74 | | UNICODE | EUC-JP | EUCJP-MS | 75 | | --------------------------- | ---------------------------------- | ---------------------------------- | 76 | | "〜" U+301C WAVE-DASH | 0xA1C1 | Encoding::UndefinedConversionError | 77 | | "～" U+FF5E FULLWIDTH TILDE | Encoding::UndefinedConversionError | 0xA1C1 | 78 | 79 | In Web applications, it depends on the client environment that the input character as "〜" is U+301C or U+FF5E. This cannot select by the application. What you can do with the application is only to determine the handling of the unencodable characters. 80 | 81 | `Wavedash` offers the option that to convert unencodable characters to resembling characters. 82 | 83 | ## Development 84 | 85 | After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake rspec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. 86 | 87 | To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). 88 | 89 | ## Contributing 90 | 91 | 1. Fork it 92 | 2. Create your feature branch (git checkout -b my-new-feature) 93 | 3. Commit your changes (git commit -am 'Add some feature') 94 | 4. Push to the branch (git push origin my-new-feature) 95 | 5.
