Best way to convert text files between character sets? What is the fastest, easiest tool or method to convert text files between character sets? Specifically, I need to convert from UTF-8 to ISO-8859-15 and vice versa. Everything goes: one-liners in your favorite scripting language, command-line tools or other utilities for OS, web sites, etc. On Linux/UNIX/OS X/cygwin: Gnu iconv suggested by Troels Arvin is best used as a filter . It seems to be universally available. Example: $ iconv -f UTF-8 -t ISO-8859-15 in.txt > out.txt As pointed out by Ben, there is an online converter using iconv. Gnu recode (manual) suggested by Cheekysoft will convert one or several files in-place . Example: $ recode UTF8..ISO-8859-15 in.txt This one uses shorter aliases: $ recode utf8..l9 in.txt Recode also supports surfaces which can be used to convert between different line ending types and encodings: Convert newlines from LF (Unix) to CR-LF (DOS): $ recode ../CR-LF in.txt Base64 encode file: $ recode...

How to check if “ ” exist? When I print a variable, I get a blank result and when I inspect the element I see that   .   I tried to check if the variables is empty or equals this value: ir( empty($string) || $string == " " || strpos($string, " ") || $string == " "){ //Do Something. } But the code inside that condition is not executed. When I var_dump($string) , I get: var_dump($string) string(2) " " What should I do to check if the variable equals or contain that? I would suggest to check for null or empty string using trim(): (!isset($string) || trim($string) === '') – wp78de Jul 1 at 6:00 (!isset($string) || trim($string) === '') what is ir ?? – smith ...
