I had a similar issue, and I solved by setting the encoding to UTF8 with \encoding UTF8 in the client before attempting an INSERT INTO foo (SELECT * from bar WHERE x=y);. My client was using WIN1252 encoding but the database was in UTF8, hence the error. More info is available on the PostgreSQL wiki … Read more
string foo = “hello world”, bar = string.Empty; foreach(char c in foo){ bar += c; } Using StringBuilder: string foo = “hello world”; StringBuilder bar = new StringBuilder(); foreach (char c in foo) { bar.Append(c); } Below is the signature of the String class: [SerializableAttribute] [ComVisibleAttribute(true)] public sealed class String : IComparable, ICloneable, IConvertible, IComparable<string>, … Read more
You can use the Index function of package strings Playground: https://play.golang.org/p/_WaIKDWCec package main import “fmt” import “strings” func main() { x := “chars@arefun” i := strings.Index(x, “@”) fmt.Println(“Index: “, i) if i > -1 { chars := x[:i] arefun := x[i+1:] fmt.Println(chars) fmt.Println(arefun) } else { fmt.Println(“Index not found”) fmt.Println(x) } }
This may not be the most elegant solution, but the simplest is probably a quick subclass of TextView with a Handler that updates the text every so often until the complete sequence is displayed: public class Typewriter extends TextView { private CharSequence mText; private int mIndex; private long mDelay = 500; //Default 500ms delay public … Read more
Swift 3/4 let string = “0kaksd020dk2kfj2123” if let number = Int(string.components(separatedBy: CharacterSet.decimalDigits.inverted).joined()) { // Do something with this number } You can also make an extension like: extension Int { static func parse(from string: String) -> Int? { Int(string.components(separatedBy: CharacterSet.decimalDigits.inverted).joined()) } } And then later use it like: if let number = Int.parse(from: “0kaksd020dk2kfj2123”) { … Read more
This is from long ago as an escape character to enable you to have consts for control characters in a more readable way. const CtrlC = ^C; begin Write(Ord(CtrlC)); end. This defines a Char constant with value #3, then writes 3 in Borland Pascal 7, and I remember seeing it years before that too. I … Read more
The W3C released an official response about when to use and when not to use character escapes which you can find here. As they are also the group that is in charge of the HTML specification, I think it’s best to follow their advice. From the section “When to Use Escapes” Syntax characters. There are … Read more
Pass a negative value as the length argument (the 3rd argument) to substr(), like: $result = substr($string, 3, -3); So this: <?php $string = “Sean Bright”; $string = substr($string, 3, -3); echo $string; ?> Outputs: n Bri
