Every second *.ass/*.srt/… (subtitles) file. Spaces are common in
directory names you know where. And in subtitles, yes.

Non-ASCII bytes in file names do not need escaping, even if your
 is UTF-8 and file has a single 0x80 byte in its name (which
is not valid UTF-8). Problematic are:

1. Globbing characters: *, ? (AFAIR forbidden on Windows), [], {}.
2. Common expansion characters: $ (not forbidden in file names, and
not uncommon as well, though I saw only some automatically created
binary files like caches with them), `.
3. Vim own expansion characters: %, #. I use them in my file names,
and you may sometimes get `%` after downloading file from the web if
name is deduced automatically.
4. Separators: space, tab. Have not seen tab, but space is very common
when origin of the file worked on Windows and file cannot be described
with one word. *nix users prefer to use underscore or hyphen-minus.
5. ASCII control characters: newline (AFAIK other do not have
problems). Have seen in a file name that was not created by me for
testing purposes when I accidentally pasted something with newline
into KDE3 file manager (konqueror?). I am not using file managers on
my PC any more though.
6. Escaping characters: backslash.

Other characters do not need escaping. Most (everything when talking
about *nix) of the above is handled by fnameescape(). See also
https://github.com/vim/vim/issues/541.

Even if you stick to safe filenames, this does not mean that
fnameescape() will do any harm. And it is more robust.

BTW, I used to have directory ~/*.* which contains many significant
files created in order not to turn ~ into a junk. It is now ~/a.a
though, but symlink `*.* -> a.a` is still there. Also see no harm in
naming books like `author-series-nr-title` where `author` is either
`transliterated_russian_name` or `%[english_name%]` (`%[` and `%]` are
present there literally), same for other fields.

You forgot `fnameescape()`: `vim -c 'execute "edit"
fnameescape(myfile)'`. In most cases this can also be written as

vim -c 'edit `=myfile`'

Unlike your variant which does not allow a huge number of characters
including spaces and `[]` which are not uncommon, `=myfile` does not
allow only newline characters inside `myfile`. Has a problem that if
`myfile` matches some pattern in `` option vim will not
open anything, so this variant is for manual uses only, for scripts
(aliases, user commands, etc: for any place which is written once)
there is fnameescape().

[Tim Chase]

add the following to your vimrc:

   let myfile='/path/to/your/file'

then you can invoke vim with

   vim -c 'exe "e ".myfile'

which is a bit awkward, so you might want to make an alias if you
intend to do it frequently.
