Check if file is EBCDIC or ASCII format

So, i have this requirement where i need to check the file format, whether it's EBCDIC or ASCII, and based on format retrieve the information from that file:

my file is:

file1.txt-->this ebcdic file
file2.txt-->ascii file

i tried below code:
Code:
file=file1.txt
type="`file $file`"

i get output if file is ebcdic:
Code:
file1.txt: data

if file is ascii:
Code:
file2.txt: ASCII text, with no line terminators

now my requirement is i need to do some operations if file is ebcdic and some if file is ascii:

Code:
type="`file $file`"
if grep -q data "$type"; then
echo "ebcdic"
else
echo "ascii"
fi

output:
Code:
grep: 010020001_S-FOR-Sort-SYEXC_20180109_062320_0100.x937: data: No such file or directory
ascii

firstly its not searching the word data correctly in $type variable and its showing something like no such file or directory, can anyone guide me where i am going wrong, and also what will the best approach for this requirement.
TIA

irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
