  // Fomantic API module has some very buggy behaviors:
  //
  // If encodeParameters=true, it calls `urlEncodedValue` to encode the parameter.
  // However, `urlEncodedValue` just tries to "guess" whether the parameter is already encoded, by decoding the parameter and encoding it again.
  //
  // There are 2 problems:
  // 1. It may guess wrong, and skip encoding a parameter which looks like encoded.
  // 2. If the parameter can't be decoded, `decodeURIComponent` will throw an error, and the whole request will fail.
  //
  // This patch only fixes the second error behavior at the moment.
