[xsl] FO: Non-proportional output with proportional font

[Christian Haase <haase@xxxxxxxxxxx>]

Hi all!

Im producing documents with standard font "Arial/Helvetica" 
(proportional font). The problem: parts of the document containing 
tables, created with ASCII characters (like - and |). Unfortunatly, I've 
no chance to re-create these stupid text-elemtens. Source of the text is 
given XML, generated on IBM Mainframe with Cobol.
Now I'm looking for a tricky way to process this text-tables, getting a 
pretty formatted output.
The easiest way is using an non-proportional font like "Courier", of 
course. But this isn't the solution I'm looking for, cause I dont want 
to use these ugly font in my documents.
Is there any chance getting a non-proportional output by using a 
proportional font (e.g. Helvetica)? I know, sounds crazy, but: any ideas?

Greetings,
Christian
