UPDATE: I seem to have found the source of the original glitch:
Since I was not aware of a way to save a .txt file normally, I was simply changing the extension on my computer using the "Get Info" tab. This ended up corrupting my text files, since they were originally rtf.
I have discovered a way to save next files normally now, but I am now experiencing an entirely different problem:
When i place the .txt files and image into the folder now, UTAU refuses to read the file altogether. I am saving the files through microsoft word using .txt, and with the settings of Unicode 6.3 (UTF-8). Does anyone know why UTAU won't read the files now? I'm wondering if i'm just using the wrong type of encoding, but i'm not sure. If anyone knows how to resolve this, it would be greatly appreciated.
Once again, I am using UTAU-Synth, which is the Mac version of the product. My character.txt file currently looks like this:
character.bmp is the current name of the image file.
