I don't understand your problem. Both .vhd and .txt files are typically
ASCII character files. You can make a copy of the .vhd file with the
Windows explorer, then change the name to *.txt and it should be what you wish.
Editors like Notepad++ are also called "text" editors because they edit text
files.
What format does Notepad++ use?
