How to check the charset of string in Java?
Strings in java, AFAIK, do not retain their original encoding – they are always stored internally in some Unicode form. You want to detect the charset of the original stream/bytes – this is why I think your String.toBytes() call is too late. Ideally if you could get the input stream you are reading from, you … Read more
Convert non-ASCII characters (umlauts, accents…) to their closest ASCII equivalent (for slug creation)
The easiest way I’ve found: var str = “Rånades på Skyttis i Ö-vik”; var combining = /[\u0300-\u036F]/g; console.log(str.normalize(‘NFKD’).replace(combining, ”)); For reference see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/normalize
What is the total number of nodes in a full k-ary tree, in terms of the number of leaves?
Think about how to prove the result for a full binary tree, and you’ll see how to do it in general. For the full binary tree, say of height h, the number of nodes N is N = 2^{h+1} – 1 Why? Because the first level has 2^0 nodes, the second level has 2^1 nodes, … Read more

What is the most accurate encoding detector? [closed]
I’ve checked juniversalchardet and ICU4J on some CSV files, and the results are inconsistent: juniversalchardet had better results: UTF-8: Both detected. Windows-1255: juniversalchardet detected when it had enough hebrew letters, ICU4J still thought it was ISO-8859-1. With even more hebrew letters, ICU4J detected it as ISO-8859-8 which is the other hebrew encoding(and so the text … Read more
Why do symbols like apostrophes and hyphens get replaced with black diamonds on my website?
It’s an encoding problem. You have to set the correct encoding in the HTML head via meta tag: <meta http-equiv=”Content-Type” content=”text/html; charset=ISO-8859-1″> Replace “ISO-8859-1” with whatever your encoding is (e.g. ‘UTF-8’). You must find out what encoding your HTML files are. If you’re on an Unix system, just type file file.html and it should show … Read more
