Is there a clever method for transforming a string into a sequence of numbers in Javascript (not just converting "0.5" to 0.5, but rather "Hello" into 47392048)?
Any suggestions are welcomed.
Many thanks!

One way to determine the numerical value of a character is by using its ASCII representation:
"Determine the ASCII value of a character".charCodeAt(0);
After carefully considering your feedback, I have come up with a potential solution that has not been extensively tested.
var str = "κόσμε 这是一条狗 é €";
$('#orig').after('<dd>' + str + '</dd>');
var result = "";
for (var i = 0, len = str.length, code, paddedCode; i < len; ++i) {
code = str[i].charCodeAt(0).toString();
paddedCode = code.length >= 8
? code
: new Array(8 - code.length + 1).join(0) + code; result += paddedCode;
result += paddedCode;
}
$('#nums').after('<dd>' + result + '</dd>');
var segments = result.match(/.{8}/g);
$.each(segments, function(k, v) {
$('#nums-segmented').after('<dd>' + v + '</dd>');
});
revertedString = '';
for (var i = 0, len = segments.length; i < len; i=i+2) {
revertedString += String.fromCharCode((segments[i] | 0));
}
$('#string').after('<dd>' + revertedString + '</dd>');
Test this code on JSFiddle.
The key to this solution is padding numbers and manipulating them as strings when necessary.
