Looks like sftp doesn't distinguish Binary files and ASCII files at all. That means it doesnt support the commands like 'bin' or 'ascii' that ftp supports.

Usage: sftp [options]...
[profile|[user@]host[#port]]Access remote files using the Secure Shell protocol.
Options:
-b buffer_size_bytes Define maximum buffer size for one
request (default: 32768 bytes).
-B batch_file Use batch file.
-D, --debug=LEVEL Set debug level string to LEVEL.
-N max_requests Define maximum number of requests sent in
parallel (default: 10).
-P port Connect to this SSH port on the remote
machine (default: 22).
-v, --verbose Use verbose mode (equal to `-D 2').
--keep-alive=VALUE Send no-operational packet to the server,
each specified amount of time.
--tcp-connect-timeout=VALUE
Overwrite default timeout value that is
used when connecting to a server.
-i file Use private keys defined in identification
file to authenticate with public key method.
--identity=ID Use private key 'id' as user identification.
The 'id' can be either key id, key hash or
a key file name.
--identity-key-id=ID Use key id as a user identification.
--identity-key-hash=ID
Use key hash as a user identification.
-K, --identity-key-file=FILE
Use key file as a user identification.
--allowed-authentications=METHODS
--aa=METHODS
Allow only selected methods in user
authentication. The 'methods' is a comma
separated list of authentication methods.
Giving value 'help' lists available methods.
--kip Same as '--aa=keyboard-interactive,password'.
-c, --ciphers=CIPHERS Allow only selected ciphers to be used.
Giving value 'help' lists available ciphers.
--macs=MACS Allow only selected MACs to be used.
Giving value 'help' lists available MACs.
--kexs=KEXS Allow only selected KEX methods to be used.
Value 'help' lists available KEX methods.
--hostkey-algorithms=HOSTKEYALGORITHMS
Allow only selected hostkey algorithms to be
used. Value 'help' lists available hostkey
algorithms
-C Disables compression.
+C Enables zlib compression.
--compressions=METHODS
Allow selected compression methods.
Giving value 'help' lists available methods.
--exclusive Opens always a new connection, does not share
connection.
--fips Performs checksums using the FIPS
cryptographic library.
--password= Set user password. Giving the PASSWORD
PASSWORD| directly as the argument is not secure!
file://FILE| Give either a path to FILE containing the
extprog://PROG password, or a path to external program
that will output the password.
--plugin-path=PATH Set plugin path to PATH. This is only
used in FIPS mode.
-V, --version Display program version and exit.
