const TextDirectionHeuristicCompat!	ANYRTL_LTR If the text contains any strong right to left non-format character, determines that the direction is right to left, falling back to left to right if it finds none.
const TextDirectionHeuristicCompat!	FIRSTSTRONG_LTR Determines the direction based on the first strong directional character, including bidi format chars, falling back to left to right if it finds none.
const TextDirectionHeuristicCompat!	FIRSTSTRONG_RTL Determines the direction based on the first strong directional character, including bidi format chars, falling back to right to left if it finds none.
const TextDirectionHeuristicCompat!	LOCALE Force the paragraph direction to the Locale direction.
const TextDirectionHeuristicCompat!	LTR Always decides that the direction is left to right.

Constants

ANYRTL_LTR

Added in 1.1.0

const val ANYRTL_LTR: TextDirectionHeuristicCompat!

If the text contains any strong right to left non-format character, determines that the direction is right to left, falling back to left to right if it finds none.

FIRSTSTRONG_LTR

Added in 1.1.0

const val FIRSTSTRONG_LTR: TextDirectionHeuristicCompat!

Determines the direction based on the first strong directional character, including bidi format chars, falling back to left to right if it finds none. This is the default behavior of the Unicode Bidirectional Algorithm.

FIRSTSTRONG_RTL

Added in 1.1.0

const val FIRSTSTRONG_RTL: TextDirectionHeuristicCompat!

Determines the direction based on the first strong directional character, including bidi format chars, falling back to right to left if it finds none. This is similar to the default behavior of the Unicode Bidirectional Algorithm, just with different fallback behavior.

LOCALE
