If you mean exclude raspap ssid, $ap_ssid is defined here:
raspap-webgui/includes/wifi_functions.php
Lines 66 to 69 in f5a18b8

Ah, \x00-\x1f are the first 32 unprintable 7bit ASCII control codes. \x7f = delete and the rest are extended ASCII ISO Latin-1 printable characters.
The latter shouldn't be excluded as the IEEE 802.11 standard allows SSIDs with 0-32 octets of an unspecified or utf-8 encoding. So for example råsþi÷wêbgüî is a valid SSID.
