astralLetterAndMarks top-level constant

String const astralLetterAndMarks

Unicode's astral planes consist of the supplementary code points that are outside of the Basic Multilingual Plane (BMP).

These are represented in UTF-16 (which Dart strings use) with surrogate pairs.

This pattern captures a vast range of characters from various scripts and symbol sets present within these astral planes, ensuring comprehensive coverage for many ancient scripts, specialized notations, and more.

Due to the breadth and complexity of the astral planes, the exact scripts and characters matched by this pattern span a diverse range. For specific details on which characters are matched, it is advisable to refer to the Unicode code charts, cross-referencing with the hex values provided in the pattern.
