libdata-uriencode-perl 0.11-3 (arm64 binary) in ubuntu oracular

 The world of the web works off of URI's. The Query string portion of
 URIs already support encoding of key/value paired data - they just
 don't natively allow for complex data structures.
 .
 There are modules or encodings that do support arbitrarily complex
 data structures. JSON, YAML and Data::Dumper all have their own way
 of encoding complex structures. But then to pass them across the web,
 you usually still have to URL encode them and pass them via a form
 parameter.
 .
 Data::URIEncode allows for encoding and decoding complex (multi
 level) data structures using native Query String manipulators (such
 as CGI.pm). It takes complex data and turns it into a flat hashref
 which can then be turned into a URI query string using URL
 encoding. It also takes a flat hashref of data passed in and
 translates it back to a complex structure.
