There is no programming interface in the core of Tk that supports
multi-font, multi-line text; support for that behavior must be built on
top of simpler layers.

Note that the interfaces described here are
byte-oriented not character-oriented, so index values coming from Tcl
scripts need to be converted to byte offsets using the
\fBTcl_UtfAtIndex\fR and related routines.

A glyph is the displayable picture of a letter, number, or some other
symbol. Not all character codes in a given font have a glyph.
