why I have to transfer same php script in binary now?

I had developed a script, earlier I use to transfer it directly without any transfer mode selection, recently i developed and improved it, now I have to transfer it via binary mode, I am using same ftp client (FileZ开发者_运维问答illa), but i have changed my ide from phpDesigner to netbeans.

Can anybody Please explain me why is this happening, and a solution to it, as it is causing problems to me because i cant distribute it freely without any documentation.

Thank You.

Is your new IDE using a character encoding that looks like binary to Filezila.

eg, if you were using ascii and are now using utf16, then every other byte in the file is likely to be a zero, which filezilla will see as a binary file.
