Using curl in two environments I found a different behaviour. Not sure if this is related to the OS, the shell or curl itself. So, posting here for your consideration.
*Environment A.*
	Local machine. 
	+ OS version:    ```Windows 8.1 Enterprise 64bits```
	= Shell version: ```Microsoft Windows [Version 6.3.9600]```
	= curl -V:
        ```curl 7.28.1 (i386-pc-win32) libcurl/7.28.1 OpenSSL/1.0.0j zlib/1.2.7 libidn/1.18 libssh2/1.4.2 librtmp/2.3
        Protocols: dict file ftp ftps gopher http https imap imaps ldap pop3 pop3s rtmp rtsp scp sftp smtp smtps telnet tftp
        Features: AsynchDNS GSS-Negotiate IDN Largefile NTLM SSL SSPI libz```
*Environment B.*
	Azure VM Cloud Machine.
	+ OS version:    ```Windows Server 2012 R2 Datacenter```
	= Shell version: ```Microsoft Windows [Version 6.3.9600]```
	= curl -V:
        ```curl 7.28.1 (i386-pc-win32) libcurl/7.28.1 OpenSSL/1.0.0j zlib/1.2.7 libidn/1.18 libssh2/1.4.2 librtmp/2.3
		Protocols: dict file ftp ftps gopher http https imap imaps ldap pop3 pop3s rtmp rtsp scp sftp smtp smtps telnet tftp
		Features: AsynchDNS GSS-Negotiate IDN Largefile NTLM SSL SSPI libz```
		
Given the commented environments, the following command:	
   ```curl -k -o src.zip "https://appworks2devel.blob.core.windows.net/jobs/ff80ad05-1d64-4dd8-a9be-147dd7f1889d/code/App.zip?sv=2012-02-12&st=2014-09-17T08%3A24%3A33Z&se=2014-09-17T12%3A29%3A33Z&sr=b&sp=r&sig=%2FFdVnkl7Qql3grpK6iGFVMkFTsmwKfKc%2BG0KdRIU3%2Fo%3D"```
Result: 
  - Fails on Environment A.
  - And works on Environment B.
Error report on A follows:
```

Reading a bit more about encoding on DOS shells some people recommends to scape  & in DOS to be ^&. Therefore the fixed command would be:
   ```curl -k -o src.zip "https://appworks2devel.blob.core.windows.net/jobs/ff80ad05-1d64-4dd8-a9be-147dd7f1889d/code/App.zip?sv=2012-02-12^&st=2014-09-17T08%3A24%3A33Z^&se=2014-09-17T12%3A29%3A33Z^&sr=b^&sp=r^&sig=%2FFdVnkl7Qql3grpK6iGFVMkFTsmwKfKc%2BG0KdRIU3%2Fo%3D"```
Result: 
  - Works on Environment A.
  - And fails on Environment B.
  Error on B:
  The URL is invalid: breaks the signature and downloads an invalid file instead the real one.
There is a way to make this work in both platforms with a unique syntax?
What is the recommended form?
Thank you.
