Function UriDecodeUnchecked

extern/nfd/nfd_portal.cpp:987–999

Decodes the given URI and writes it to `outPath`. The caller must ensure that the given URI is not malformed (typically with a prior call to `TryUriDecodeLen`). This function does not write any trailing null character.

// not malformed (typically with a prior call to `TryUriDecodeLen`).  This function does not write
// any trailing null character.
