PHP83 doesn't handle multi-byte encoded XML correctly.

[Shigio YAMAGUCHI]

It was found that libxml2 version 2.13.0 and later does not
handle UTF-8 tag names correctly. This appears to have been
the cause of the PHP's bug.

Can you revert libxml2 of Macports to one of the stable
versions (libxml2 2.12.*)? There must be a lot of outages
happening all over the world due to this bug.

The results of 'test' program are shown below.
(I have attached 'test.cc' to this email.)

[libxml2 2.12.9]
This version works correctly.

$ c++ -O -I/usr/local/2.12.9/include/libxml2 -L/usr/local/2.12.9/lib
-lxml2 test.cc -o test
$ ./test
text1

[libxml2 2.13.0]
This version does not work.

$ c++ -O -I/usr/local/2.13.0/include/libxml2 -L/usr/local/2.13.0/lib
-lxml2 test.cc -o test
$ ./test
XPath error : Invalid expression
/文書
 ^

[libxml2 2.13.4 (the current version of Macports)]

This version does not work too.

$ c++ -O -I/usr/local/2.13.4/include/libxml2 -L/usr/local/2.13.4/lib
-lxml2 test.cc -o test
$ ./test
XPath error : Invalid expression
/文書
 ^

Thanks,
Shigio
