Actually, you'll see that Unicode itselfs makes some usage of PUAs, but not part ofthe Unicode standard itself.
Look at the CLDR, for example in the transliteration schemes for InterIndic: these PUAs are used as intermediate codesfor the transliteration from/to Indic scripts, even if they could conflict with other PUAs found in documents and that the transliterator should not affect.
Insn't there a way to make the CLDR InterIndic use exclusively the subsets of characters it is supposed to convert?
This raises a question about the validity of the presence of the "InterIndic" PUA encoding in the CLDR... Probably those PUAs could be encoded using one of the standard Indic scripts only. This is always possible in transliterators, by using a finite-state automata, where intermediate states for the Latin-to-Indic are represented by strings containing zero or more Indic characters followed by zero or more Latin characters. You don't need any PUA to represent these internal states!
