Android apprently parses the string and interprets it as connection parameters for wifi leaving only password (removing encoding such as escape characters), sfos is correct in reading the whole string the backslash is there, it’s more of a missing feature to identify strings in this format as special ones that need interpretation (assuming this is actually a standard as the link provided by @cnlpete just says ‘we propose’, no idea if this is officially recognized as one or just something android does)
So one can extract the valid access codes ‘by hand’ out of the scan result and simply ignore the backslash and not worry about wrong data.

Missing feature: I second that.
- My X Android with QR-Droid doesn’t show the backslash.
- SFOS native camera app + BarCode show the backslash.
- Removing the backslash in Notes and then using QR-Clip to generate a QR, BarCode doesn’t show the backslash.
So, since BarCode identifies this as wifi-access, it could clean up the strings…
