OK, thanks.  Currently the MediaWiki module handles two cases.

(1) MediaWiki.Markup reads an Oberon Text and produces markup which 
produces a page which imitates the original Text.  ETH Oberon has the 
Courier font.  Markup for characters in the Courier font will be 
tagged <span style="font-family: Courier, monospace; ...">. To my 
knowledge, a contemporary browser is likely to recognize "Courier"; if 
Courier is not available another monospace is likely to be substituted.
The output syntax is in the MediaWiki module at line 37.

https://en.wikibooks.org/wiki/Oberon/A2/Oberon.MediaWiki.Mod 

The conversion of the Text typeface attribute to the HTML tag begins at 
line 266. "IF extantAttr.typeface # globalAttr.typeface ..." This 
conversion process is satisfactory.

(2) To produce markup for a text from a PDF, the original Oberon Text 
is not directly available. Probably typeface can be extracted from PDF; 
I don't know how. The PDF reader displays the document but doesn't  
give me attributes.  

Visually I can recognize serif vs. sans serif and fixed pitch vs. 
variable pitch.  Then I can impose a typeface.  My MediaWiki module 
has a simple means to do that; not yet in the book.

My immediate question: what font-family specification for serif, 
variable pitch will be recognized by most browsers?  An answer will 
allow me to complete case (2).

Thx,                                  ... P. L.
