+that is, overall_ink_return.height <= \-overall_ink_return.y. +The overall_ink_return for a nonkerned character +is entirely at, and to the right of, the origin; +that is, overall_ink_return.x >= 0. +A character consisting of a single pixel at the origin would set +overall_ink_return fields y = 0, x = 0, width = 1, and height = 1. +.LP +If the overall_logical_return argument is non-NULL, +it is set to the bounding box that provides minimum spacing +to other graphical features for the string. +Other graphical features, for example, a border surrounding the text, +should not intersect this rectangle. +.LP +When the +.ZN XFontSet +has missing charsets, +metrics for each unavailable character are taken +from the default string returned by +.ZN XCreateFontSet +so that the metrics represent the text as it will actually be drawn. +The behavior for an invalid codepoint is undefined. +.LP +The function +.ZN Xutf8TextExtents +is an extension introduced by The XFree86 Project, Inc. in their 4.0.2 +release.
