ASS_FEATURE_BIDI_BRACKETS constant
int
const ASS_FEATURE_BIDI_BRACKETS
Match bracket pairs in bidirectional text according to the revised Unicode Bidirectional Algorithm introduced in Unicode 6.3. This is incompatible with VSFilter and disabled by default.
(Directional isolates, also introduced in Unicode 6.3, are unconditionally processed when FriBidi is new enough.)
This feature may be unavailable at runtime (ass_track_set_feature may return -1) if libass was compiled against old FriBidi.
Implementation
static const int ASS_FEATURE_BIDI_BRACKETS = 1;
