Thanks for appreciation. Could you implement this?

They are low-active bit flags. And it is intended to be used for
capability detection if needed, although currently not being
used.

UTextExtent_Unspecified = -1,  /* ..1111 */
UTextExtent_Full        = -2,  /* ..1110 */
UTextExtent_Paragraph   = -3,  /* ..1101 */
UTextExtent_Sentence    = -5,  /* ..1011 */
...

enum UTextExtent
bridge_text_acquisition_capability(void)
{
  /* low-active OR */
  return ~(~UTextExtent_Full | ~UTextExtent_Line | ~UTextExtent_Paragraph);
}


/* low-active input AND */
if (~bridge_text_acquisition_capability() & ~UTextExtent_CharFrags) {
  ...
}
