|
||
If the bug involves quotes being curled the wrong way, please send example
|
||
text to illustrate.
|
||
|
||
|
||
### Algorithmic Shortcomings ###
|
||
|
||
One situation in which quotes will get curled the wrong way is when
|
||
apostrophes are used at the start of leading contractions. For example:
|
||
|
||
'Twas the night before Christmas.
|
||
|
||
In the case above, SmartyPants will turn the apostrophe into an opening
|
||
single-quote, when in fact it should be a closing one. I don't think
|
||
this problem can be solved in the general case -- every word processor
|
||
I've tried gets this wrong as well. In such cases, it's best to use the
|
||
proper HTML entity for closing single-quotes (`’`) by hand.
