Wide string — c.WString(n)

Fixed-size UTF-16LE wchar slot. The argument n is the character capacity (byte size is n * 2). Reads and writes little-endian UTF-16 unless the buffer looks like mis-encoded UTF-8 (see implementation notes in source).

@c.struct()
class Label {
  @c.field(c.WString(32))
  text!: string;
}

C equivalent (64 bytes on disk):

typedef struct {
    wchar_t text[32]; /* UTF-16 code units, NUL-terminated; 32 × 2 = 64 bytes */
} Label;

On platforms where wchar_t is not 16-bit, the same layout is uint16_t text[32];.
