Comment 6 for bug 1755020

This commit does not change the previous behavior. It fixes a potential incorrect behavior.

IPC-D-356 is a ASCII file, with a very poor syntax.
IPC-D-356A is not really better.

Documentation does not explain how to code non ASCII7 chars (unicode chars if you want) in ASCII files.
UTF8 is one way to code them.
Gerber files use an other way.
Unfortunately, UTF8 is not used in Windows, and gives not easily readable ASCII files, unless you have a text editor on Windows that can use UTF8 coding.

I am reluctant to use in a fabrication file a coding convention not usable on Windows, but only on Unix.

Net names in netlist are not free. They have serious constrains, depending on the software that use this netlist.
