Readers of this thread might like to know of the following earlier thread.
Recently, being interested in this project, I produced the following.
This is entitled Tuffy6 Ligatures Pack A1. It is usable as a stand-alone font if so desired, yet my hope is that the glyphs will be used by others when producing more advanced versions of Tuffy.
Some of the ligatures are regular Unicode and some are Private Use Area, yet they could be useful now and would be there in case Tuffy is at some time in the future converted to OpenType format.
I started from a copy of Tuffy6.ttf mentioned in the previous post.
As I do not have the hinting facilities I produced the file by starting with a copy of Tuffy6.ttf, adding new glyph positions, producing the designs using copies of some of the glyphs that are already there, then deleting most of the original glyphs.
I have been thinking of the whole issue of a public domain font which can be extended by anyone who so chooses.
Readers might like to consider the following.
That page has many links.
Now please consider the following.
Now please consider using the two together, with DVB-MHP (Digital Video Broadcasting - Multimedia Home Platform) broadcasts being used in a "black box" with the laptop providing a screen, keyboard and mouse! A DVB-MHP system "set-top box" contains a built-in font with a minimum repertoire: there is also a facility where fonts can be broadcast. Recent versions can use OpenType fonts.
Now intellectual property rights isues are going to arise in many cases, yet for Tuffy the font is public domain, so if a specialised font for some minority language is needed, then Tuffy could be used!
Thus Tuffy could perhaps find round-the-world use as a broadcast font for minority language groups for distance education.
This thought has made me think that I should try to develop the public domain font which I started and encourage others to develop it too so that it too could potentially be a round-the-world broadcast font.
