Have you ever downloaded a really great resourcepack and the font that comes with it just sucks?
Or just wanted to have a custom font, like Comic Sans MS, without having to install mods or hacked clients for that?
Well, here is your solution!
Based on this (http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-tools/1263246-minecraft-font-converter-use-any-fonts-in) thread on Minecraft Forum, which is really old and not updated, I decided to create my own tool, since the one the guy created didn't include special characters, such as ã, ç, â, ä, etc.
So, my version includes ALL the characters that are present in a minecraft resourcepack (ascii.png, maybe will do the other too, soon).
Open the file that you will download, and then you should have this interface:
Click on the first 'Select...' button, to open a file selector, and select a '.ttf' or '.otf' font file to be used:
After selecting the font, you should have something like this:
Now click the second 'Select...' button to choose the output folder (where the resourcepack will be saved!):
Then, you choose the resolution (32px, 64px, 128px, 256px or 512px):
(Note that 256px and 512px might take a bit to render the image)
After that, click the 'Create pack!' button, and wait!
After the process is finished, you will get a message like this:
It means it's all done, and you can go to the output folder that you selected before:
Just copy that file, and put it into '/.minecraft/resourcepacks/'!
Open Minecraft, go to Options -> Resource Packs, and select the pack you just created!
