The selected character set is chosen to minimize problems due to the many platforms a release may encounter during its distribution.
Since FTP servers, operating systems or file systems may not allow special characters in file or directory names, only a small set of characters is allowed.

When choosing file size, the limiting factor is the size of the media to be used (such as 700MB for CD-R).
The standards are designed such that a certain amount of content will fit on each piece of media, with the best possible quality in terms of size.
Correctly named folders make it easier to maintain clean archives and unique filenames allow dupecheck to work properly.
There's a defined character set which can be used in naming of the folders.
If more discs are required for sufficient quality, the standard will define the circumstances where it is acceptable to expand to a second or third disc.
Newer video standards moved away from the size constraints and replaced them with a quality based alternative such as the use of CRF.
Because of this, modern playback software can easily play a release directly from the packaged files, and even stream it as the release is downloaded (if the network is fast enough).
MP3 and music video releases are an exception in that they are not packaged into a single archive like almost all other sections.
The reason for this is that some material compresses much better than others.
