why couldn't they just use normal URL query param escaping? Always reinventing the wheel, badly.
WIFI:t=wpa&s=My%20Network&p=secret%20word
would have been much better.
- ircop420 4y agoData is expensive in QR land or your resulting QR code becomes larger in size, requiring more physical space to display. URL encoding has a lot of overhead. Also '\' escaping has preceded the existence of URLs. I'm not sure who is doing the reinventing here.
- silvestrov 4y agoOnly encoded characters take up more space and you don't have to escape: quotation mark, semicolon, comma, colon or backslash. So I think the difference is small. QR codes can contain quite a bit more information than what's needed for WIFI name and password.
- SCLeo 4y agoIn countries that do not use English as the main language, it is fairly common to have non-English SSIDs. URL encoding is incredibly inefficient when encoding those characters.
- nemetroid 4y agoAt equal printed sizes, QR codes with less information are much easier/more forgiving to scan.
- danachow 4y agoQR code is not particularly dense (like compared to something like a hard drive) - why waste space that could not be put towards more redundancy (error correction)?
