I rarely update the C library. Kernel + libraries + OS programs are a single unit here, updated about once a year, and then by many people and with all the usual testing. I could lookup how often some locale was modified, but honestly, I'm too lazy now. | (but of course SQL_ASCII is a mistake). Really? I re-read the chapter on Locale/CharSet Support, and I don't see the mistake. Only one can not convert that to anything else, which is fine in this usecase (storing arbitrary filenames from any OS in any character-set within the same column). regards, PMc
