Not all Extended Ascii Characters are being converted to ASCII

Question

Using icu4j-63.1 library we are transliterating native text to ascii character for our project. For few of the cases transliteration is not working as expected.

Please let me know if I am missing something here.

Below code is being used to transliterate

Transliterator any2Latin = Transliterator.getInstance("Any-Latin/UNGEGN; Latin; Title");
Transliterator latin2Ascii = Transliterator.getInstance("Latin-ASCII");
latin2Ascii.transliterate(any2Latin.transliterate(<<Input String>>))

Below are the list of sample text for which transliteration is not working ie., the input and output string both are same.

• THE L±NFANT TRUST (Expected to transliterate ± to +/-. But the output is same as the given string).
• DON¢A
• JAIME CASTA¦ON
• ENGº JOSE BARATA
• TERRY STUARDCB¬NEWTONRAY¬
• ¥YOUNG© (Here, © is successfully being converted to (C) but not Yen symbol. The Yen symbol remains the same post transliteration)
