I am pretty shure, I tested the capability of filenames on a Linux (ext2)

The outcome was, that you can use 254 different characters, except the
'\0' and the '/'.
But I agree, it is an annoyance it should be forbidden. ;)
The person who invented that spaces and other unprintable characters were
allowed in filenames and paths should be found, his PC and iPhone should be
confiscated, he should be exiled to an isolated island in the middle of the
Arctic Ocean, and he should be nominated for an IgNobel. The person at
Microsoft who decided that "C:\Program Files" was an acceptable place to
install programs should be sent along as his butler.
What a stupid thing to say.
My comment was meant as light and humorous. I am sorry that it was misunderstood, and
sorry that you feel like starting to call names. Relax.
You can use those things on pretty much every file system and OS.
1) not without quoting them, you can't. Which is the whole point.
and
2) which does not mean that it was a good idea to start with, nor that it is a good idea
to keep going along with it. The layout of the keys on the computer keyboard on which you
are now typing was designed originally for mechanical writing machines, and its purpose
was to slow down typing, so that the levers would not cross eachother. Does it still make
sense ? no. Do we keep on using them ? yes.
Ever
since your grandmother started using a computer and thought it was
pretty darn stupid for young whippersnappers like yourself to tell her
that she couldnt name a file "good recipies".
Sir, you flatter me. Being called a young whippersnapper hasn't happened to me in a long,
long time.
My grandmother - peace to her soul - never even heard about computers. But had she used
them, she could also not have saved a file named "bills/to-pay", nor a file named "good
recipes" (she could spell) written in the special reddish ink color that she used in her
cookbooks.
And had she wanted to call me on the telephone, she would have had to dial a number
composed of the digits 0-9, she could not have just typed my name.
A special place in hell is reserved for programmers that write code
that assumes that spaces and other unprintables are illegal in a
filename.
If that is their only sin, then I'd assume that this special place would be rather nice,
relatively speaking. And I'd happily join them, because I freely admit that I have made
that same mistake several times (in my youth of course). But it is probably pretty crowded.
Let me put this another way. Would you be willing to have your salary docked, until it has
paid for the time lost over the last 20 years, due to mistakes inadvertently made by
programmers with 10 years or more of experience, in failing to properly quoting paths or
filenames because they could have spaces in them ?
Or to put in yet another way : would you publically declare here that you have *never*
yourself made such a mistake ?
It has also been a while since I have personally programmed something without taking this
fact into account. Which does not mean that I like it. And I have seen several generations
of programmers working for me, who are still making that same mistake.
The point is that one must take it into account, and has to add extra programming steps
*every time* to take this into account. And it did not necessarily have to be so.
If "\0" and "/" or "\" and "<" and ">" and "|" and "&" are disallowed in filenames on most
systems, I fail to see how disallowing spaces would be such a dramatic drawback. But I
can easily imagine how disallowing spaces in filenames would save the world many thousand
work hours every year. Would you pretend the opposite ?
Like the keyboards, it can probably not be changed anymore, so we are stuck with it. But I
often think nostalgically about what would have happened (or not happened) if that
original designer had just said "hey, let's not allow spaces in paths and filenames; they
can use underlines instead".
