  21 Note about the OSC addresses and the Faust UI names:
  22 ----------------------------------------------------
  23 There are potential conflicts between the Faust UI objects naming scheme and
  24 the OSC address space. An OSC symbolic names is an ASCII string consisting of
  25 printable characters other than the following:
  26         space
  27 #       number sign
  28 *       asterisk
  29 ,       comma
  30 /       forward
  31 ?       question mark
  32 [       open bracket
  33 ]       close bracket
  34 {       open curly brace
  35 }       close curly brace
  36
  37 a simple solution to address the problem consists in replacing
  38 space or tabulation with '_' (underscore)
  39 all the other osc excluded characters with '-' (hyphen)
  40
  41 This solution is implemented in the proposed OSC UI;
