Manpages VT\-IS\-UTF8Section: Linux User's Manual (1)Updated: 10 Aug 1998 Index Return to Main Contents NAMEvt-is-UTF8 - check whether current VT is in UTF8- or byte-mode.SYNOPSISvt-is-UTF8 [-h|--help] [-V|--version] [-q|--quiet]DESCRIPTIONvt-is-UTF8 checks whether the current VT is in UTF8 mode, by writing (and erasing afterwards) a 3-byte-long UTF8 sequence, and looking how much chars where displayed by the console driver.A message telling in which mode the console is is then written to stdout (except if the --quiet option was given). If the --quiet option is not given, the value returned is 1 if an error occurs, else 0. OPTIONS
BUGSThe check should be done by directly asking the kernel, which is not possible as of kernels 2.0.x.As of kernel 2.0.35, the byte-mode is sometimes erroneously detected as UTF8-mode, after switching from a 512-chars font to a 256-chars font. This is probably a console-driver bug. SEE ALSOunicode_start(1), unicode_stop(1).
