#1850 new defect

Design new caps to be resilient against human transcription errors.

Reported by: nejucomo Owned by: davidsarah
Priority: normal Milestone:
Component: code-encoding Version: 1.9.2
Keywords: newurls usability standards uri Cc:
Launchpad Bug:


One important aspect of this ticket is to define the use cases that should be covered, for example reading over a phone or writing down on paper.

I suggest important use cases are:

  • cut'n'paste errors, such as:
    • dropping characters off the front or end
    • including characters outside the cap, especially whitespace
  • link-generation-software parsing:

One suggested solution is internal checksums.

Of course I'm biased in my suggestions having made some cut'n'paste errors that lead me to believe my data had been corrupted. ;-)

  • Component changed from unknown to code-encoding
  • Keywords newurls added; newcaps removed
  • Milestone changed from undecided to 2.0.0

This is strictly speaking a design issue for new URLs, rather than new caps.
