Transliteration with Iconv in Ruby

问题:

When I'm trying to transliterate a Cyrillic utf-8 string with

Iconv.iconv('ascii//ignore//translit', 'utf-8', string).to_s

(see questions/1726404/transliteration-in-ruby)

I'm getting everything but those symbols that have to be transliterated.

For example: 'r-строка' → 'r-' and 'Gévry' → 'Gvry'.

What's wrong?

Ruby 1.8.7 / Rails 2.3.5 / WSeven

回答1:

require 'iconv'
p Iconv.iconv('ascii//translit//ignore', 'utf-8',  'Gévry') #=> ["Gevry"]
# not         'ascii//ignore//translit'

For Cyrillic the translit gem might work.

It seems the solution is too tricky for me. Problem solved using stringex gem.

Another way is to create custom translit by tr and gsub methods of String without using iconv.

# encoding: UTF-8

def russian_translit(text)
    translited = text.tr('абвгдеёзийклмнопрстуфхэыь', 'abvgdeezijklmnoprstufhey\'')
    translited = translited.tr('АБВГДЕЁЗИЙКЛМНОПРСТУФХЭ', 'ABVGDEEZIJKLMNOPRSTUFHEY\'')

    translited = translited.gsub(/[жцчшщъюяЖЦЧШЩЪЮЯ]/,
        'ж' => 'zh', 'ц' => 'ts', 'ч' => 'ch', 'ш' => 'sh', 'щ' => 'sch', 'ъ' => '', 'ю' => 'ju', 'я' => 'ja',
        'Ж' => 'ZH', 'Ц' => 'TS', 'Ч' => 'CH', 'Ш' => 'SH', 'Щ' => 'SCH', 'Ъ' => '', 'Ю' => 'JU', 'Я' => 'JA')
    return translited
end

p russian_translit("В чащах юга жил бы цитрус? Да, но фальшивый экземпляр!")
#=> "V chaschah juga zhil by tsitrus? Da, no fal'shivyj ekzempljar!"
