net-ldap 0.12.0 - 0.12.1 dropped support of UTF-8
Issue #17618 (migration to net-ldap 0.12), dropped support of UTF-8, I always get Encoding::CompatibilityError ACSII-8BIT and UTF-8 (for any language except english of cource).
And you catch this error here #21453 and fixed by adding force_encoding (maybe there was need to stop and check net-ldap).
net-ldap 0.13 fixed for this, but dropped support ruby 1.9.3 (RM 3.2 still support).
So, just info for others devs, which need to make any LDAP connections and read data.
Commit from net-ldap 0.13 https://github.com/ruby-ldap/ruby-net-ldap/commit/ecce488daed676351b561e39a2dae1147983c939
class Net::BER::BerIdentifiedString def initialize args super current_encoding = encoding if current_encoding == Encoding::BINARY force_encoding('UTF-8') force_encoding(current_encoding) unless valid_encoding? end end end
Its take my 3 hours to find error and try to fix this (not just simple force_encoding, was need general solution). Save your time.
