Example input

name=Ada Lovelace&note=50% ready

Expected output

name=Ada%20Lovelace&note=50%25%20ready

Reproducible method

  1. Preserve the original and create the smallest representative sample.
  2. Run a strict parse or validation before transformation.
  3. Record options, compare counts and structure, then test in the receiving system.

Common error

Encoding a complete URL hides separators; double encoding changes percent signs.

Reduce a failure while retaining the problematic structure; this separates malformed input from unsupported behavior.

Technical limitation

Hostnames, paths, forms, and query components follow different rules.

A successful preview does not remove format ambiguity or downstream requirements.

Security and privacy

Reject unsafe schemes and keep tokens out of query strings.

Local processing reduces transfer risk but cannot protect a compromised browser, unsafe extensions, clipboard history, or later misuse.
