I need to remove chilean currency symbol from the quotes. See image:

I understand the "Ch" on the side of the $ sign may be part of an international nomenclature format, but here in Chile we dont use it. We only use the "$" sign, and this is confusing my customer. Some of them have enen thought I'm charging them in another foreign country currency!

Please help me remove it. If not from the entire system, at least from PDF quotes and invoices.

Thank you!
