Fiddler Auth Inspector should decode BASIC credentials using Encoding.UTF8 not Encoding.Default

Fiddler’s “Auth” Inspector uses Encoding.Default() for decoding base64-encoded BASIC auth credentials. This was common practice at the time this was first written but is now obsolete., written much later, demands UTF-8.

Chromium and Firefox encodes credentials using UTF-8.;l=89;bpv=1;bpt=1

Hey Eric,


The fix will be released with the upcoming new release of Fiddler Classic. The new version will use UTF-8 instead of the Default encoding option.
