transform non-english text

Hugo

1/19/2007 9:19:00 AM

Hello,
I have a Ruby aplication that deals with non-english text and I want to
transform some of that text to [^a-zA-Z0-9].
Examples:
búsqueda -> busqueda
presenças -> presencas
für -> fur
avião1 -> aviao1

Call anyone help me?

Thanks.
Best regards,
Migrate

I don't think there is a unified mapping table to transform non-[^a-zA-Z0-9]
characters into a specific one of them. But if you can concider to write a
map yourself try something like:


class String
MAP = [[/ü/, 'u'],
[/ö/, 'o']]

def eng_char
res = String.new(self)
MAP.each { |r| res = res.gsub(r[0],r[1]) }
return res
end

end

s = "abücüöö"
puts s + " => " + s.eng_char

----------
Will output:

abücüöö => abucuoo

You could try with Iconv to convert from your encoding to ASCII. Quick
example :

>> require "iconv"
=> true
>> Iconv.iconv("ascii//translit", "iso-8859-1", "aéioù")
=> ["a'eio`u"]
>> Iconv.iconv("ascii//translit", "iso-8859-1", "aéiou")[0].tr('^a-z', '')
=> "aeiou"

Hello,

Thanks for your help.

I will try both approaches to see what fits best.

iconv translit is really nice... when it works. It works on our FreeBSD
server but not on my ubuntu dev machine. Your mileage may vary.
