add -encoding utf8 to javac call

Hi Laszlo,

seems like javac doesn't like your name in a clean chroot without any locale set (C).

See https://buildd.debian.org/status/fetch.php?pkg=libnumbertext&arch=arm64&ver=1.0~beta2-2&stamp=1526164029&raw=0:

CLASSPATH=. javac -source 1.8 -target 1.8 org/numbertext/Numbertext.java

so we should probably add a encoding -utf8 to the javac call. Did so in Debians 1.0~beta2-3.
