Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

I started to use timewarrior. It seems to me that I track my time. timew
command accept Unicode(Japanese) tag. timew summary outputs are also
fine.

But, When I try to do "timew day", my machine looks freezing.
Because timew command grub 24G virutal memory.

yabuki@yelona:~$ ps auxww | grep -i timew
yabuki    1360 21.8 94.7 25179664 7554388 pts/0 D+  22:23   1:05 timew
day
yabuki    1386  0.0  0.0  12264   988 pts/1    S+   22:28   0:00 grep -i
timew

strace -p 1360
strace: Process 1360 attached
strace: [ Process PID=1360 runs in x32 mode. ]
strace: [ Process PID=1360 runs in 64 bit mode. ]
mmap(NULL, 17179873280, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = 0x7f7f6d498000

I used 英語 tag. 英語 means English in Japanese Kanji.

I'd like to use unicode tag. That is why I reported.

Best regards
Yukiharu.
