Jay Berkenbilt a478cbb6dc Silently/transparently recognize UTF-16LE as UTF-16 (fixes #649) 
The PDF spec only allows UTF-16BE, but most readers seem to accept
UTF-16LE as well, so now qpdf does too.
 2022-02-15 16:13:12 -05:00
Jay Berkenbilt 1065bbb016 Handle odd PDFDoc codepoints in UTF-8 during transcoding (fixes #650) 
There are codepoints in PDFDoc that are not valid UTF-8 but map to
valid UTF-8. We were handling those correctly with bidirectional
mapping.

However, if those same code points appeared in UTF-8, where they have
no meaning, they were left as fixed points when converting to PDFDoc,
where they do have meaning. This change recognizes them as errors.

Jay Berkenbilt cb769c62e5 WHITESPACE ONLY -- expand tabs in source code 
This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.

In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.

Jay Berkenbilt 5f3f78822b Improve use of std::unique_ptr 
* Use unique_ptr in place of shared_ptr in some cases
* unique_ptr for arrays does not require a custom deleter
* use std::make_unique (c++14) where possible
 2022-02-05 11:24:56 -05:00
Jay Berkenbilt f727bc9443 PointerHolder: add get() and use_count() for forward compatibility 
PointerHolder will be replaced with shared_ptr, so let people start
moving.
 2022-02-04 13:12:37 -05:00
Jay Berkenbilt f76191f0c2 Add array test to PointerHolder 2022-02-04 13:12:37 -05:00
Jay Berkenbilt b02d37bc0a Make QPDFArgParser accept const argv 
This makes it much more convention to use the initializeFromArgv
functions since you can use string literals.

Jay Berkenbilt 3b60224bae JSONHandler: pass JSON object to array start function 2022-01-31 15:57:45 -05:00
Jay Berkenbilt ce3406e93f JSONHandler: pass JSON object to dict start function 
If some keys depend on others, we have to check up front since there
is no control of what order key handlers will be called. Anyway, keys
are unordered in json, so we don't want to depend on ordering.

Jay Berkenbilt 901e3e4fbf QPDFArgParser: remove unused copyFromOtherTable 
This was used, but it no longer is, so let's not keep the extra
complexity around.
 2022-01-30 13:11:03 -05:00
Jay Berkenbilt 76c4f78b5c Add QUtil::make_shared_cstr 
Replace most of the calls to QUtil::copy_string with this instead.
