Currently, I'm using CFStringTransform to convert Java-based strings

Works brilliantly.
Luckily, these files are short and this function is super fast.
This enables me to naively take all the text of a file provided or
copied and pasted and convert it whole in one pass.
My question is, will this function handle AttributedStrings?
Presumably not.
Is there a lazy way to handle this ?
(since this function is super good about recognizing and
transforming only string ranges that it targets)
or is it going to require me coming up with an equivalently clever
way of determining the ranges of attribute runs to make this
practical??
You can try creating an NSMutableAttributedString and then calling
CFStringTransform on its -mutableString. Some CF functions (e.g.
CFStringTrimWhitespace) screw up the attributes when you do this, but
it's worth a try.
