Обсуждение: Inconsistent Conversion Names
I thought you had named the conversion functions after the IANA names. I found the following inconsistencies, however: sjis should be shift_jis win1250 should be windows_1250 (similarly 866, 1251) koi8r should be koi8_r I think we should fix this now. -- Peter Eisentraut peter_e@gmx.net

It actually matches "Windows-31J" in IANA, which is too ugly to being emploied as our conversion name, IMO. > win1250 should be windows_1250 (similarly 866, 1251) I agree with win1250 -> windows_1250, win1251 -> windows_1251, but do not agree with renaming win866. There's no windows_866 in IANA. Maybe that should be "ibm866"? > koi8r should be koi8_r Someone said that the conversion table is actually koi8r + koi8u, being different from IANA's koi8_r. Not sure though. -- Tatsuo Ishii

Is it ibm866 or are you wondering yourself? > Someone said that the conversion table is actually koi8r + koi8u, > being different from IANA's koi8_r. Not sure though. I found mention in the archives by Oleg B. that it is in fact koi8_r. -- Peter Eisentraut peter_e@gmx.net

I know CP866, CP-866,IBM866,IBM_866 IANA isn't a standard but a recommendation. glibc uses name mangling, so KOI8-R -> koi8r > > > Someone said that the conversion table is actually koi8r + koi8u, > > being different from IANA's koi8_r.

We're not talking about your system. :-) Do you know whether PostgreSQL's conversion tables cover koi8-r or koi8-u or both? The documentation contains contradicting information about that. Actually, since we use the officially provided Unicode conversion tables, we should know what they cover. -- Peter Eisentraut peter_e@gmx.net
