Contributed by: John Fultz

ResourceFunction["VisualizeSpanningCharacters"][type]

returns a table displaying spanning character data of the specified type.

ResourceFunction["VisualizeSpanningCharacters"][]

returns an Association of all character data types.

ResourceFunction["VisualizeSpanningCharacters"][type,"RawData"]

returns the raw data for type.

Details and Options

Supported type values are "Horizontal", "Vertical" and "Diacritical".

This data is pulled from the installation layout in the file SystemFiles/FrontEnd/TextResources/FontMap.tr.

Diacritical characters are designed to simulate a diacritical when used as a script in Overscript or Underscript.

Display horizontal spanning character data:

In[1]:=

Display all spanning character data:

In[2]:=

Return raw data used to construct the table:

In[3]:=

Out[3]=

The current implementation assumes all spanning characters are in the Unicode plane 0. Future Wolfram front ends may violate this assumption.
