请教，关于keymap。。。

LongerZ

我最近在升级时，发现init过程中，先前的"setting  terminal encoding UTF-8" 变成了"setting  terminal encoding ASCII" ，结果执行“make menuconfig”时菜单乱七八糟的，什么也看不清，还有个细节原来控制台的中文字显示为黑块，现在是乱码(很乱的那种)，我知道跟$LANG有关系，但是怎样才能恢复先前的状态？总不能每次都unset LANG吧？

# /etc/conf.d/keymaps

# Use KEYMAP to specify the default console keymap.  There is a complete tree
# of keymaps in /usr/share/keymaps to choose from.

KEYMAP="us"
#KEYMAP="la-latin1"

# Should we first load the 'windowkeys' console keymap?  Most x86 users will
# say "yes" here.  Note that non-x86 users should leave it as "no".

SET_WINDOWKEYS="no"


# The maps to load for extended keyboards.  Most users will leave this as is.

#EXTENDED_KEYMAPS="backspace keypad euro2"


# Tell dumpkeys(1) to interpret character action codes to be
# from the specified character set.
# This only matters if you set UNICODE="yes" in /etc/rc.conf.
# For a list of valid sets, run `dumpkeys --help`

DUMPKEYS_CHARSET=""


# Some fonts map AltGr-E to the currency symbol ¤ instead of the Euro €
# To fix this, set to "yes"

FIX_EURO="no"
