UTF8 support

[devfelipereis]

Hello! Thanks for this great project.

I need to use characters like "ç", "é", etc... When I print with that, I get something like "chinese" characters.

Is it possible with this lib? Or is this a limitation of my printer(I'm testing in a "Kinup KP-1019")?
Obs: I'm new with this.

Thank you!

I'm thankful for your contribution.

Well, I'm not sure that the cause is the lib or the printer. But, you can figure out it, by a simple test.
The BufferBuilder uses the ascii encode, but you can change it to utf8 and test if it works.

escpos-xml/lib/buffer-builder.ts

Lines 120 to 124 in 8ff6546

	public printText(text: string): BufferBuilder {
	this.buffer.write(text, 'ascii');
	return this;
	}

I tested printing a text "ç" and "õ" with utf8 encoding, but the printer was not able to print it correctly, printing a chinese character instead.

Hello. Thanks for the instructions.

Ten minutes ago I was also testing.
Not working for me either.
I have the same result as you.
