    Description

      JDK-8291660 (jdk20) enhanced character iterator to handle grapheme clusters (a.k.a. user-perceived characters per https://unicode.org/reports/tr29/ ), yet javaFX renders these clusters as a sequence of symbols.

      For example:

      🤦🏼‍♂️ - \ud83e\udd26\ud83c\udffc\u200d\u2642\ufe0f
      ☝🏿- \u261d\ud83c\udfff
      🇯🇵 - \ud83c\uddef\ud83c\uddf5
      ❤️ - \u2764\ufe0f

      I think we need to bring javafx in line with the latest BreakIterator behavior.
