quote characters in luatex

quote characters in luatex

[Thomas A. Schmitz]

In my experiments with luatex, there's one thing that may be  
surprising for many users: we have come to expect that the characters  
` and ' in our input files map to single left and single right  
quotation marks. luatex just typesets them "verbatim," so to speak.  
It converts the combination `` and '' to double quotation marks,  
however. So my question: wouldn't it make sense to convert the single  
marks as well? (And please don't tell me "Oh but you should use \quote 
{} instead of ` '." I know that, but I guess that many users have  
hundreds of old documents where they use `'. Moreover, ' also creates  
the apostrophe character, which cannot be avoided.)

Best

Thomas

there is a feature:

texligatures=yes

for the rest, we can consider mappings but i fear that we end up in a 
quote mess

is that the same as tlig=yes ? This doesn't effect the single quote.  
I see the problem with the "quote mess"; in the old pdfTeX, it wasn't  
even possible to get the ' character at all. But it is a minor  
anoyance in terms of backward compatibility, I think.

these quote thingies were actually font hacks, and depended on the 
fontencoding and such, which makes files non portable

well, we can make a converter, much simpler than the greek debabelizer -)

What, even simpler! :-)

Of course, it could also be done via Arthur's code for a fea file.  
I'm just wondering if this behavior should be made the default.
