Bech32, the encoding of BIP-173, on both platforms.

A Bech32 text has a prefix that a person reads, the separator 1, and
data in an alphabet of 32 characters. The last six characters of the
data are a checksum. The names of Nostr are Bech32, as NIP-19 defines
them.

The section Segwit address format of BIP-173 tells how eight bits of
data go into characters of five bits. Bech32m, the checksum of BIP-350,
isn't here.

The reading of a file by the ranges of its bytes that a reader needs,
fetched in rounds within limits, for the readers of views.

A reader of a view gives the ranges that it lacks, and read! fetches
them and reads again, until the reader has what it needs. The bytes come
from a fetch function: an http/fetcher for a file on the web, or a
fetcher of a local file or a Blob.

Views of files whose bytes come in parts, for the readers of media files
and images, on both platforms.

A view holds the parts of a file that are there, each at its offset. A
reader asks the view for the ranges that it needs before it reads them.
A range that the view doesn't hold throws an exception that holds the
ranges, so that the caller can fetch them and read again. A range past
the end of the file throws too. The fetching is in util.bytes.ranges.

The requests of podcast-clj, which name it as their User-Agent unless
they name another, e.g. by the :user-agent option.

Character and entity references in the text of feeds, HTML's included,
which XML alone doesn't know.

The JSON adapter (RFC 8259): strings in, plain data with string keys out,
and back, on both platforms.

The keys of podcast-clj's maps, from the camelCase names of XML and
JSON.

The Ring requests that the handlers of podcast-clj answer and the
responses they give: the bodies, credentials, hosts and conditions of
the requests.

Dates and durations as they appear in feeds, parsed leniently and
formatted canonically, from arithmetic and regular expressions alone so
that the JVM and JavaScript agree.

Instants are inst values, java.util.Date or js/Date. Durations and
timestamps within media are seconds: a long when whole, and a double
otherwise.
