Online Upper Case Converter

I have a debian based server and I moved a big html site from a windows based server over.

On windows, it's not case sensitive so I didn't have any 404 issues coming up. But whenever moving the site over to debian certain directory and files with capital letters are having issues.

I'd like to know if there is a command that allows me to rename all files and directories under the main public html directory to be lowercase? Everything I've tried from searching is not really working.

In my Android application I have different EditText where the user can enter information. But I need to force user to write in uppercase letters.Do you know a function to do that?

In Turkish, there's a letter İ which is the uppercase form of i. When I convert it to lowercase, I get a weird result. For example:

var string_tr = "İ".toLowerCase();var string_en = "i";console.log( string_tr == string_en );  // falseconsole.log( string_tr.split("") );     // ["i", "̇"]console.log( string_tr.charCodeAt(1) ); // 775console.log( string_en.charCodeAt(0) ); // 105

"İ".toLowerCase() returns an extra character, and if I'm not mistaken, it's COMBINING DOT ABOVE (U+0307).

How do I get rid of this character?

I could just filter the string:

var string_tr = "İ".toLowerCase();string_tr = string_tr.split("").filter(function (item) {    if (item.charCodeAt(0) != 775) {        return true;    }}).join("");console.log(string_tr.split(""));

but am I handing this correctly? Is there a more preferable way? Furthermore, why does this extra character appear in the first place?

There's some inconsistency. For example, in Turkish, there a lowercase form of I: ı. How come the following comparison returns true

console.log( "ı".toUpperCase() == "i".toUpperCase() ) // true

while

console.log( "İ".toLowerCase() == "i" ) // false

returns false?

I have problem in changing a string into uppercase with Python. In my research, I got string.ascii_uppercase but it doesn't work.

The following code:

 >>s = 'sdsd' >>s.ascii_uppercase

Gives this error message:

Traceback (most recent call last):  File "<console>", line 1, in <module>AttributeError: 'str' object has no attribute 'ascii_uppercase'

My question is: how can I convert a string into uppercase in Python?

I have a string

x <- "lowerUpper"

and want do determine if and which character within this string is an uppercase letter.

I can use toupper(x) == x, which tells me if all characters are uppercase, but how do I check if only some (and which) are?
