Example to produce Russian in gofpdf

nonLatinTest.go

package main

/*
To correctly produced in the output PDF the input string "Молоко и творог"
which is Russian, use codepage 1251; must also do the following:
- use the unicode translator method in gofpdf
- in the specifed font directory must be the following:
	1. cp1251.map: the codepage mapping
	2. helvetica_1251.z: font file (from the gofpdf project)
	3. helvetica_1251.json: font descriptor file
Here is the command to run this demo:
$ go run nonLatinTest.go -c cp1251 -o cp1251.pdf
