Something like this:
PangoFontMetrics *metrics;
GtkWidget *widget;
int char_width;
int width_in_chars;
widget = GTK_WIDGET (text_view);
context = gtk_widget_get_pango_context (widget);
metrics = pango_context_get_metrics (context,
widget->style->font_desc,
pango_context_get_language (context));
char_width = pango_font_metrics_get_approximate_char_width (metrics);
width_in_chars = widget->allocation.width / char_width;
This assumes you have set the monospace font for the text view with
gtk_widget_modify_font(), resulting in a monospace font for
widget->style->font_desc; if not you need to use the font desc of
interest, not widget->style->font_desc.
