No, they are processed in the exact same way. However, as pointed out in
the later messages in this thread, the shell can make this bit more
complex due to quotation marks being processed at that level.

With most shells, this would end up trying to send the SSID without
quotation marks which wpa_supplicant will then try to interpret as a hex
string (all strings can be configured either as quoted ASCII text or
hex dump without quotation marks).

Well, yes, it should. I did not bother adding extra validation for the
string being an integer and this is just "interpreted" with atoi() and
atoi() returns 0 when it doesn't find initial digits from the string..
Taken into account that there are only three valid options here, this
could be replaced with couple of if statement or a switch statement..
