NAME

       vt-is-UTF8  -  check  whether  current  VT  is  in  UTF8- or byte-mode.
       檢查當前VT是否處於VTF8模式或是字節模式.

`覽
       vt-is-UTF8 [-h|--help] [-V|--version] [-q|--quiet]

yz
       vt-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.    vt-is-UTF8
       檢查當前VT是否處於  UTF8  模式,  其方式是寫(並且隨後擦除)  一 3 字節的
       UTF8 序列, 然後察看控制台驅動展示了多少茼r符.

       A message telling in which mode the  console  is  is  then  written  to
       stdout     (except     if    the    --quiet    option    was    given).
       然後會在標準輸出上給出一茷H息,  指出控制台所用模式(除非給出了   --quiet
       選項).

       If the --quiet option is not given, the value returned is 1 if an error
       occurs, else 0.  在有錯誤發生時, 如果沒有選取 --quiet 選項, 返回N是 1
       , 否則將是 0 .

項
       -h --help
              display   version   number,  a  short  help  message  and  exit.
              展示版本號, 以及一蚋眶u的幫助信息, 然後退出.

       -V --version
              display version number and exit.  展示版本號然後退出.

       -q --quiet
              do not print on stdout in with mode we are, but return the state
              as  exit-status 1 if in UTF8-mode, 0 if in byte-mode. In case of
              error, 0 is returned and  a  message  is  displayed  on  stderr.
              不在標準輸出上列印所處模式,     但是返回一茠牯A,    對於    UTF8
              模式該退出狀態為 1 , 而對於字節模式該狀態為  0  .  如果發生錯誤,
              也返回 0 , 並且送給標準錯誤一茷H息.

BUGS

       The  check  should  be done by directly asking the kernel, which is not
       possible           as           of            kernels            2.0.x.
       模式的檢查可能應該通過直接請求核心來進行,         但從核心        2.0.x
       開始這就不可能了.

       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.  從 2.0.35 的核心開始,  在做了從
       512  字符字型到 256 字符字型的切換後, 字節模式有時會被錯誤地認為是 UTF8
       模式. 這或陷N是一荓惆謋x驅動的 bug .
