Note about the OSC addresses and the Faust UI names:
----------------------------------------------------
There are potential conflicts between the Faust UI objects naming scheme and 
the OSC address space. An OSC symbolic names is an ASCII string consisting of
printable characters other than the following:
	space 
#	number sign
*	asterisk
,	comma
/	forward
?	question mark
[	open bracket
]	close bracket
{	open curly brace
}	close curly brace

a simple solution to address the problem consists in replacing 
space or tabulation with '_' (underscore)
all the other osc excluded characters with '-' (hyphen)

This solution is implemented in the proposed OSC UI;
