8 years ago Hi Pratik. I'm currently working on a web app where you can create the fonts. If you cannot wait until it is finished, here is a very hacky version of the future tool in java:
package ch.squix.FontConverter;

import java.awt.Font;
import java.awt.Graphics;
import java.awt.GraphicsEnvironment;

import java.io.PrintStream;
import java.nio.ByteBuffer;
import java.nio.CharBuffer;
import java.nio.charset.Charset;
import java.nio.charset.CharsetDecoder;
import java.nio.charset.CoderResult;

I have been trying to add new font with The Dot Factory Tool, but rendering is not proper, How do you add fonts?
