R12 form builder frmbld.sh problem.

The problem that I had with this frmbld.sh is, it can't open existing files.

Solutions:
Unset LANG environment or

Add the following in $ORACLE_HOME/bin/frmbld.sh   just before the line $ORACLE_HOME/bin/frmbld $*

## Check LANG variable for UTF character set
if echo $LANG | /bin/grep -i '\.utf.*8' > /dev/null
then
export LANG=`echo $LANG | /bin/sed 's#\.[u|U][t|T][f|F].*8.*##'`
fi
