… UTF-8 to UTF-16 in fragmented data scenarios. Also part of Apple's current libdispatch: The UTF-8 to UTF-16 transformation was skipping BOM characters (`0xFEFF`) whenever they were encountered, regardless of their logical position in the data. This caused incorrect behavior when: - Data was split across multiple chunks in `dispatch_data_apply` callbacks - A BOM appeared in the middle of the data (offset > 0) The bug occurred because the BOM skip check only examined the character value (`wch == 0xfeff`) without verifying it was at the logical start of the data.
