Android "[\\p{InCombiningDiacriticalMarks}\\p{IsLm}\\p{IsSk}]+" regex compilation fails (works localy)

Question

I am following the correct answer from here: Remove diacritical marks (ń ǹ ň ñ ṅ ņ ṇ ṋ ṉ ̈ ɲ ƞ ᶇ ɳ ȵ) from Unicode chars to ,as you may expect, normalize some Strings.

It works great against local unit test, but when I try to use it on the emulator I get:

           Caused by: java.util.regex.PatternSyntaxException: U_ILLEGAL_ARGUMENT_ERROR
          [\p{InCombiningDiacriticalMarks}\p{IsLm}\p{IsSk}]+

                ... 7 more

Any ideas what is wrong?

Remove all `Is` prefixes from the Unicode category names – Wiktor Stribiżew Feb 09 '18 at 12:37 — Wiktor Stribiżew, Feb 09 '18 at 12:37
BTW, for combining marks, you may use `\p{M}`, too. – Wiktor Stribiżew Feb 09 '18 at 12:46 — Wiktor Stribiżew, Feb 09 '18 at 12:46
