In parse_count multiple units start with the same letter, so it would match different units depending on the order they were sorted when iterating over them.
This function is orignally used for determining file extensions of DASH
formats. Now in DASH, ext is determined by mime_type. See #8766 for more
information.
This is much more robust than just using regexps, and handles all
the common scenarios, such as empty/no values, repeated attributes,
entity decoding, mixed case names, and the different possible value
quoting schemes.
1. Renamed to encode_base_n()
2. Allow tables longer than 62 characters
3. Raise ValueError instead of AssertionError for invalid input data
4. Return the first character in the table instead of '0' for number 0
5. Add tests
With cn_verification_proxy, our http_response() is called twice, one from
PerRequestProxyHandler.proxy_open() and another from normal
YoutubeDL.urlopen(). As a result, for proxies honoring Accept-Encoding, the
following bug occurs:
