Given our current spaceflight capabilities, I doubt that this will be a problem for a long time. Any and all intelligent aliens are proving their intelligence by staying a long way from Earth.

From what I think to remember is, that surrogate pairs are mostly used for special symbols and that most language symbols will fit in the base page.
It does not solve my Problem, but it answers my question

That's true for earth. But wait til we add a zillion more languages which is my point =)

If we assume, say, 1000 characters per language, that means another 100 million characters which should not be a problem since a 32-bit range should handle 4G characters. At 1K characters per language, UTF-32 should accommodate 4M languages. That is, unless I am looking at this incorrectly which is certainly possible.

You're probably right. There's a bunch of reserved bitfields though but yeah, even then.
Forgive me, it's early here. =)

Things will get really interesting if/when we encounter a civilization that does not utilize language in the written ways that we do. We might come across one that has no eyes and does not sense light. It might communicate telepathically and have no written language, only thoughts. That could be really weird.

The working group committee on unicode already scrapped three preliminary recommendations on that.

I mean, my first thought was UTF-64, but drugs? I suppose drugs could work.

If we have a Universal Translator or Babel Fish we won't care what the original language looked like / sounds like / brain-waves like because we would hear / see / think it in our own ways, so Unicode would be overkill even for Earth languages. Then all we would need is a universal programming language if H T CW hasn't completed it first.

The emoji jungle would be finally cleared up because the Unicode guys & gals would finally got something useful to do rather than keeping themselves occupied for the sake of keeping themselves occupied.

Reminds me of Halloween: Venom giving out my favorite favor to the tykes => mashed potatoes (by the scoop). Well, they did say "Trick OR Treat". If they don't like it and cry, we could viper cheeks dry and let them slither off to the next door

All of this because microsoft doesn't expose the tables they use behind char.IsLetter() and the like 
Like, did they think nobody would ever need to use the unicode category codes for things?
Their enumeration isn't even flags.
for(var i = 0;i<char.MaxValue;++i)
{
char ch = unchecked((char)i);
var uc = char.GetUnicodeCategory(ch);
switch(uc)
{
case UnicodeCategory.ClosePunctuation:
_AddTo(working, "Pe", ch);
_AddTo(working, "P", ch);
break;
case UnicodeCategory.ConnectorPunctuation:
_AddTo(working, "Pc", ch);
_AddTo(working, "P", ch);
break;
case UnicodeCategory.Control:
_AddTo(working, "Cc", ch);
_AddTo(working, "C", ch);
break;
case UnicodeCategory.CurrencySymbol:
_AddTo(working, "Sc", ch);
_AddTo(working, "S", ch);
break;
case UnicodeCategory.DashPunctuation:
_AddTo(working, "Pd", ch);
_AddTo(working, "P", ch);
break;
case UnicodeCategory.DecimalDigitNumber:
_AddTo(working, "Nd", ch);
_AddTo(working, "N", ch);
break;

And on that note, why couldn't they expose the Number class?
There are many times I would have liked that.

I'm just happy to have biginteger.
now if only they'd give us a bigreal.

You're a programmer. Write it yourself.
Here's a start:
class BigReal : IComparable<BigReal>, IEquatable<BigReal>, IConvertible, IFormattable
{
public bool sign { get; private set; }
public long biasedExponent { get; private set; }
public List<ulong> mantissa { get; private set; }
}

I don't have the math skills for that.
Ever done an efficient multiply on an arbitrary length FP?
I know it's not easy.

The best algorithm depends on the size(s) of the mantissa and the size of the machine word. See the MPFR package for details.
I have written multiplication algorithms using the standard O(N^2) method, Karatsuba's O(N^lg3) method, and the Fourier transform O(N*lg(N)*lg(lg(N))) methods.
Recently, an algorithm was described for an O(N*lg(N)) method, but I can't say that I understand it.
The big problems are actually division and square root. They can be implemented using an fma (fused multiply add), which calculates A*B+C with only one rounding (for the addition).
