* the corresponding font is available. In this case it is

* NO UCS4 STRING! The only "character" of the string simply denotes

* the code point of the symbol in the font. Therefore you have to

|
* be very careful if you pass \c draw to any function that takes a

* docstring argument.
|
|
* If \p name is a known symbol, but the corresponding font is not
|
|
* available, or if it is a function name, then \c draw contains a
|
|
* regular UCS4 string (actuallay \c draw == \c name) that is painted
|
|
* on screen.
