LDAP/LDIF UTF-8 friendly regexp

[mahlonsmith]

You can't require 'ldap/ldif' at all in ruby 2.0 due to an invalid multibyte range.

Possible alternatives:

• Use utf characters instead for the range (patch included)
• Add a 'n' flag to the regexp to enforce US-ASCII
• Don't use a range at all and use String.ascii_only?, though that would break 1.8 compatibility.

Hello @mahlonsmith, sorry that it took me so long to respond, but how did you tested regex?

I see that it works correctly in version 1.8.6 and 1.8.7 but do not work in 1.9.1, 1.9.3 and 2.0.0

1.9.3p429 :001 > require 'ldap'
 => true 
1.9.3p429 :002 > require 'ldap/ldif'
 => true 
1.9.3p429 :003 > LDAP::LDIF.parse_file('./test/data/ldif8.txt')
