I'm using the 'latest beta' (1.6.1 build 180) and Controller v188.8.131.52, osx 10.8.now, Spark Standalone. When I input non standard characters like é, ç. using a USA English standard mac keyboard. 3 things happen.
1) the font used in the 'application' level (load/save dropdowns, Project Name dialog, etc, the top bar of the plugin) doesn't display characters in a readable manner, might be using its own characters, might be a rendering bug? It just doesn't look right.
2) the CDM Plugin Display (the representation of the hardware display in the software plugin) doesn't display the non-standard characters at all.
3) the CDM Hardware itself displays whatever characters were last displayed before loading the string with nonstandard characters when it encounters them. ie: load project abc123, load new project abcééé, CDM hardware displays: abc123
It's been noted that the forthcoming v1.7 will include a new browser for Project/Kit/Insrtuments. I hope this helps inform that effort.
