Re: Re: IDNA: is the specification proper, adequate, and complete?

Copy&Paste operations from  such legacy applications into other applications
may not preserve the intended character glyph informations  determined by  char sets+font sets.
That will pose another interoperablility problems to end users.

Some OS-addon/applications has it own proprietary legacy char set/locale, but share the same code space with ASCII
and use ASCII-mapped font-substitution to implement their legacy char sets, for example, in order to
implement CJK supports in English-only windows or linux. I found some other examples in Indic char sets.
 
In General, informations about assumed/system-wide font sets  
  are not available to applications  or not interpretable  with machine intelligence.

These kinds of font usages should be discouraged in IDN specifications ?
