Are you kidding?

If someone tried to sell me printer paper at the price that a dollar bill costs (a dollar -- by pure coincidence, maybe), I'd laugh in their face!

A dollar for a tiny scrap of paper like that? I'd want at least 20 A3 sheets of baxter stock!

gotta wonder with inflation and the actual price of making money when $1000 notes will make a comeback.

many countries have already dropped their 1 cent coins, too expensive, not that useful.

in fact even some banks complained, cost of counting, wrapping and storing them was more than their value - they could almost save money by throwing them away.

after many otherwise intelligent sounding suggestions that achieved nothing the nice folks at Technet said the only solution was to low level format my hard disk then reinstall my signature. Sadly, this still didn't fix the issue!

The English half pence coin (as opposed to the old ha'penny) was immensely useful -- for plumbing!

It was precisely the right size for making a stop-end out of a simple compression fitting! That made it worth about 75x its value when using it to pay for stuff!

If some idiotic-list-making web-site were to make a list of the world's most useful coins, betcha it'd be right up there at the top!

in the early 70's my father bought a brand new car for exactly $2500. (even had the optional AM radio!!)
being a salesman he clocked it in just over 2 years and traded to the new model.

about 15 years later he said he saw it on a used car lot for $2500.
yeah he had a good memory for the plate numbers, had a lot of cars, could recall every one

also had exactly 1 mobile phone, with a phone number he never remembered,
... then again that made sense: only ever had it's battery charged up exactly once

So .NET uses 16bit unicode by default, and with the territory comes the possibility of 32 bit codes embedded as surrogate pairs.

That's all well and good even if it complicates things.

However, .NET provides no functions for operating on those 32-bit values.

No char.IsWhiteSpace(). No GetUnicodeCategory(), nada.

So what the hell are you supposed to do with these values?

Char.ConvertFromUtf32(Int32) Method (System) | Microsoft Docs[^]

Okay yes, but once i have that converted (either to a 32bit int, or a double-char string, i can't do anything with it.

I can't call char.IsWhiteSpace with it.

I can't do anything but print its value. Which is stupid

I've encountered a weird one. But I don't remember if it was a surrogate or not. I just remember it didn't print to the console properly (it cooked it) or didn't save to source as a literal value or something.

It came up as whitespace, but only when I used these huge "not ranges" which are like [^a-z] (anything but a lower case letter)

that "anything" part created ranges all throughout the 16-bit unicode spectrum.

And that's when I ran into issues with one whitespace character.

I am using those.

The category for surrogates is surrogate. Not helpful.

Combining a hi and lo surrogate you get a 2 char string.

The 2 char string cannot be queried for its unicode category in .NET AFAIK

It is a mess, but, check this against what you expect, now:

public void PrintUniCodeRange(int sc, int ec)
{
    bool isKey;
    
    string key = "";

    for (int i = sc; i <= ec; i++)
    {
        string ucString = char.ConvertFromUtf32(i);
        
        isKey = i < 256;

        if (isKey) key = ((Keys)Enum.Parse(typeof(Keys), i.ToString())).ToString();

        UnicodeCategory cat = Char.GetUnicodeCategory(ucString, 0);

        if (cat != UnicodeCategory.OtherNotAssigned)
        {
            Console.WriteLine($"#{i} | Unicode Category: {cat} {(isKey ? "! Keys Enum: " + key : "")}");
        }
