10.0-BETA3, why it was added

Just a quick update on why -BETA3 was added to the 10.0-RELEASE
schedule:

A problem was discovered in the base iconv(1), which introduces a major
regression with character encoding, specifically with malformed output.

Sample code to reproduce the issue:

 % perl -e "print pack('C*', 0xa5,0xa2,0xa5,0xe1,0xa5,0xea,0xa5,0xab); \
	print qq/\n/;" \
        | iconv -f euc-jp -t utf-8 \
        | iconv -f utf-8 -t euc-jp \
        | hexdump -C
 00000000  a2 a5 e1 a5 ea a5 ab a5  0a
 00000009

While there are no compile-time issues in general, this makes the base
iconv(1) unusable with certain character sets.  Solutions are being
evaluated.

For the immediate time, -BETA3 builds have started.
