I'm not aware of any faults with MakeUEF V2.4. It now records a creators signature in UTF8, which will look like ANSI if you only use the common characters.
Worth knowing, thanks. I may add a couple of tests for UTF-8 in chunk &0, then. UTF-8 will likely also be needed for chunk &1 (game instructions/manual or URL), although not much is done yet with that chunk in TOHv3.


In other news, I am reminded that there is another mistake in the UEF 0.10 spec to go along with the bad example for chunk &114 I mentioned above. I'm just adding chunk &112 (integer gap) support to tibetuef.php, so I can synthesise some test UEFs for it. The UEF spec for &112 says

A value of n indicates a gap of 1/(2n*base frequency) seconds.

This is patent nonsense, and instead should almost certainly read n/(2*base frequency) seconds, i.e. an equivalent number of 2400 Hz cycles [technically (2000000 / 832) Hz cycles, or ~2403.846]. I think TOH-3.1 has this correct already, but we'll find out once I have some test UEFs.
