I was today years old when I learned that <a name="anchorname"></a> does not work for anchors anymore, but you can just use the id attribute of any HTML tag and your #anchorname just jumps to that element
Whitespace in filenames is a major category error IMO.
OTOH, filenames themselves (and filesystems as presently incarnated) are also grossly insufficient for many needs. It's interesting to note, for example, that on Android (and possibly iOS), databases (usually sqlite) have emerged as the de-facto default persistent data storage mechanism, even for content which would normally be held on a filesystem.
I've long been looking at questions such as what a document-oriented filesysem (#docFS) or the World Wide Web as fileystem accessible (#webFS) might look like.
For documents, I've generally arrived at a naming standard which uses underbars (_) to separate elements, hyphens (-) for standard whitespace, and double dashes (--) to indicate punctuated / multiple element (e.g., multiple authors, or a subtitle following a colon or dash). Permitted characters are otherwise 7-bit ASCII alphanumeric ([A-Za-z0-9], with dot as a file extension only, and possibly parentheses.
That might have a publisher or journal title added (additional underbar-delimited element after the title(s). Additional contributors (e.g., editors, translator) might be mentioned. And it's possible some identifier (ISBN, OCLC, DOI, LoC call number) might be added, though those are supplemental.
The idea isn't to fully and completely or precisely represent all aspects of a document or work, but to usefully do so. So yes, that means that foreign charactersets aren't presented, that full author lists aren't included (for scientific paper these can number in the tens to hundreds), etc. But enough to find the work reasonably within a corpus through a directory listing.
Yeah, I'm familiar with Calibre, Zotero etc., and should really get more familiar with them. But they're clunky enough and not sufficiently universally available (e.g., on Android, where most of my documents live these days, via an e-book reader) that I'm not optimistic they're really a solution.

@augieray@donmelton Today somebody accidentally sneezed in my face at the market. I was wearing a mask and didn’t worry about covid or flu or whatever. I accidentally sneezed in my mask passing somebody and they weren’t wearing a mask but I’m sure they were relieved I had one on.
