You will also see the low and high byte values needed to reproduce the character. They are displayed both in hexadecimal and decimal formats. Pressing Save saves a tiny file called "address.txt" that contains the low and high bytes in decimal format. Then you can run a separate program called "Show Unicode". It will read 'address.txt" and display the Unicode character very large, both as a text character and as a drawn character. Note that drawn characters lose any embedded color. Check the code of Show Unicode to see how to display Unicode characters in your own programs.
You will need all of the attached png buttons below. Put them in a folder called "Fontview".
One more thing. The box at the lower left shows the high byte address as a decimal. It points to the current location. It is set to start at 26h, which is 38 dec. This is an area of the Unicode table that contains some interesting and colourful emoticons.
I intend the user to be able to input new values from 0 to 254 inclusive, and move to that location in the Unicode table. But the textbox will not accept user input, and I don't know why. I have checked and rechecked the code, and will need Mr. K's help to resolve.
Code: Select all
