A more complete and working version of mb_sprintf and mb_vsprintf. It should work with any
"ASCII preserving" encoding such as UTF-8 and all the ISO-8859 charsets. It handles sign,
padding, alignment, width and precision. Argument swapping is not handled.
<?php
if (!function_exists('mb_sprintf')) {
function mb_sprintf($format) {
$argv = func_get_args() ;
array_shift($argv) ;
return mb_vsprintf($format, $argv) ;
}
}
if (!function_exists('mb_vsprintf')) {
/**
* Works with all encodings in format and arguments.
* Supported: Sign, padding, alignment, width and precision.
* Not supported: Argument swapping.

$encoding = mb_internal_encoding();

$format = mb_convert_encoding($format, 'UTF-8', $encoding);
$newformat = ""; // build a new format in UTF-8

$format, 2, PREG_SPLIT_DELIM_CAPTURE) ;
$newformat .= mb_convert_encoding($pre, $encoding, 'UTF-8');
