chcp advanced

The standard/native windows chcp.exe changes the codepage for the input and output encoding, and shows the input encoding. It's inflexible if you need to experiment with codepages.

If using < or > , receiving input or output from a file, the input and/or output codepage can matter and can be helpful to see what the output codepage is, and perhaps a program has changed the output codepage and not the input codepage, or to something different than the input codepage.

chcpa stands for chcp advanced, and just does the natural thing of letting you change either the input codepage, or the output codepage, or both. And it shows you both the input and output codepages

That also helps you better understand what is going on if you are doing any kind of testing to see if you have an input or output codepage issue

I may elaborate on usefulness later. suffice it to say, a program might change the output encoding and you wouldn't know from chcp
