Sorry if this belongs in the Math section, but it kind of seeps into both. I was wondering what are the most commonly displayable. Sure, most of them can display whatever's on the keyboard, but what else? Some computers back in the day were capable of displaying things like ², «», ±, °, √, ≤, etc. Now, they have much more advanced functionality, capable of displaying obscure symbols like ►,₪,↔,∕,⌡,∂,⅝, etc. But what's the limit to these symbols? Would they be able to display Unicode characters like ⁶ (superscript 6),₍ (subscript left parenthesis), or even ℏ (reduced Planck's constant)? I don't think so. So what would be the most common set of characters that would be compatible to computers back to say, the Windows 98 era? Obviously it would be different from computer to computer, but I'm asking just for the general sets. The use of images aren't acceptable in my case. I greatly appreciate your help!

Is there some sort of website in which you can somehow enter musical notes and it will play the music? -- Nick4404 yada yada yada What have I done? 03:32, 11 April 2009 (UTC)
Sometimes when I am editing Wikipedia, I accidentally press some key combination that causes the text in the text box to become right-justified. Similar to when you edit in Wikipedias where the writing is right to left (e.g. Hebrew, Arabic). The keys involved are some combination of :
This is probably more detailed than necessary, since some of you may already know the combination. What key combination causes this, and what key combination do I need to press do undo this? My current solution is to open a new window, and copy and paste my progress into that. — Twas Now ( talk • contribs • e-mail ) 10:12, 11 April 2009 (UTC)
Are there open source platforms out there for game developing? The main idea is that I would do the "screenplay" and graphics and put it on a kind of virtual machine that would deliver the logic behind the game.-- 88.6.158.100 ( talk) 11:59, 11 April 2009 (UTC)
This isn't exactly what I'm trying to do, but it will illustrate what I'm asking well enough: http://www.cs.princeton.edu/introcs/31datatype/Rot13.java.html
In that program
char c = s.charAt(i);
complies fine. But if I replace that with
int d = s.chatAt(i); char c = d;
the code refuses to compile, and I get a "possible loss of precision" error. Why? And how can I avoid possible loss of precision errors in general?
Thanks in advance. —Preceding unsigned comment added by 137.165.246.36 ( talk) 20:08, 11 April 2009 (UTC)
d
) to a char, which stores less bits than an int. Thus if d
had a value greater than 255 (or 65535 if a char in Java is wide), it would be "trimmed" to fit inside a char, producing the "loss of precision". --

Recently I had been doing an online puzzle game which has many levels. When I got up to level 33 I, and several other people on the internet, found that the game would not allow entrance to that level, despite there being several levels beyond that. The site owner does not respond to emails. After examining the cookie for level 32 with IECookiesView by Nirsoft dot net it seems that the cookie may not work due to having an invalid date, which can be corrected with IECookiesView.
However I was busy at the time and I have now lost the cookie I had after completing level 32 (the levels have to be done in sequence). I do not want to plod through all 32 levels again. Instead I have inspected the cookies obtained after completing levels one, two, and three, and the relevant differences in the cookies are shown below:
LEVEL ONE
Key : __utma
Value : 11671083.1539782161861915000.1239481907.1239481907.1239481907.1
Key : __utmb
Value : 11671083.1.10.1239481907
LEVEL TWO
Key : __utma
Value : 11671083.1539782161861915000.1239481907.1239481907.1239482097.2
Key : __utmb
Value : 11671083.1.10.1239482097
LEVEL THREE
Key : __utma
Value : 11671083.1539782161861915000.1239481907.1239482239.1239482420.4
Key : __utmb
Value : 11671083.1.10.1239482420
Can anyone deduce what the relevant values may be for level 33 please? Note that the value for utmb for the first and second levels differs by one digit, the fourth from the end. The online game, if you are curious, is Ice Breaker by Nitrome, which was recommended by someone here. Thanks. 78.147.135.185 ( talk) 22:37, 11 April 2009 (UTC)
Thanks!!!! I did as you said and now have access to all levels, including the mysterious level 33! Design note - I hate games that require you to go through a series of levels again if you restart the game or whatever - destroys the fun completely. 78.151.152.56 ( talk) 20:47, 12 April 2009 (UTC)
You must be able to save the current level, to be able to switch the computer off and come back to it later. Save it at the end of every level, and find out where the saved file (or cookie) is placed. If you mess up the next level, delete the cookie for it, turn off the game,and it will restart at the last good level you had. SteveBaker, I don't think OP wants to start at level 100; they just don't want to do 1-30 again if their player dies on level 31.
