When I try to encode string in program I got Encoding::ConverterNotFoundError error “code converter not found (UTF-8 to KOI8-R)” (and other charsets) When I run script with encoding in ruby interpreter it work. What I have to call for loading converters? ---

Solved. It has to require “enc/trans/transdb”. ---

Please post a (hopefully short!) script which demonstrates the problem you’re having. I don’t see any mention of a cp866 charset in ruby sources, so you might just be SOL there. > transcoder table from my program: > (gdb)p \*transcoder\_table > $3 = {type = 0x7ffff75632c0, num\_bins = 11, entries\_packed = 0, > num\_entries = 1, bins = 0x704170, head = 0x7077b0, tail = 0x7077b0} > > transcoder table from ruby interpreter: > (gdb) p \*transcoder\_table > $2 = {type = 0x7ffff7dc32c0, num\_bins = 19, entries\_packed = 0, > num\_entries = 84, bins = 0x73e190, head = 0x6cc600, tail = 0x741150} Looks like this table gets added to by encoding-related extensions, so you might have to require them before it gets the stuff you want in it. ---
