[WBH] Carrying encoding deeper than it otherwise needs to be also adds a great deal of work to insure consistency. That need is pervasive and never-ending.

Such overhead is avoidable if the lower levels remain as pure-binary and

I'm wondering about 'untrusted user input', which account for countless buffer-overflow exploits, year after endless year. Seems to me that a file name is just one more type of 'untrusted user input' to add to the pile. Anyone have any thoughts about this?
