Apostrophe in SSID name results in erroneous WFJAP=? response

Question

When trying to connect to SSID with a non-utf8 apostrophe (in our case, it's the "right single quote" U+2019: https://www.compart.com/en/unicode/U+2019 ), DA16K successfully connects to the AP but then when querying WFJAP, responds with erroneous SSID ( in this case 0617061e2809973207769666 as opposed to papa's wifi) . See attached log screenshot. 
 Chip: DA16200 
 SDK: RTOS 3.2.8.5

Hi ST-Kon, Apologies for the delay. I was able to recreate this issue. The right apostrophe you tried to use is not supported. I tried to configure my Laptop (Windows) and I got the following message: The default ' character can be used and I was able to connect with the DA16200MOD EVK with this specific character.

Hi ST-Kon, 
 In the Easy Setup, as you can see, the non-printable characters in the SSID are displayed in the hex string. This is expected behavior. 
 However, we have confirmed that in the SDK v3.2.8.1, there is a problem where an SSID containing non-printable characters is sent to the host in the format of a hex string. 
 So we have made changes to fix the problem and attached the diff file. Please test this on your side and let us know if you have any issues. Best Regards, OV_Renesas 0001-changes_to_fix_non-printable_ssid_issue.zip
