pcsoft.us.windevCopyright 2026, PC SOFT28 Jul 2015 22:01:00 Z27 Jul 2015 08:52:00 ZHi A client has recently started receiving text files which contain a range of non-printing characters which we need to strip out. The exact characters vary somewhat from file to file so we need a routine to remove ASCII 1 to 31 (excluding TAB,CR & LF) and 127 upwards. I know we could loop through for each character & replace it but I'm hoping someone has a more efficient way so that we're not looping through the file 100 plus times. We have up to 30 of these files a day to deal with, up to 25Mb in size for each one.
