-   * GetSegmentAt() returns the start and the end position of the index-th

-   * (not character-offsets) of the string returned by GetText(). The range of

+   * GetSegmentOffset() returns the position of the index-th segmentation point
+   * in the composition text. The position is given by a byte-offset (not a
+   * character-offset) of the string returned by GetText(). It always satisfies
+   * 0=GetSegmentOffset(0) < ... < GetSegmentOffset(i) < GetSegmentOffset(i+1)
+   * < ... < GetSegmentOffset(GetSegmentNumber())=(byte-length of GetText()).
+   * Note that [GetSegmentOffset(i), GetSegmentOffset(i+1)) represents the range
+   * of the i-th segment, and hence GetSegmentNumber() can be a valid argument
+   * to this function instead of an off-by-1 error.
