Try to guess the real width of a string, see comment in the patch.

Without this patch, we'd get something like this:

01 03:16 我的地盘 (My Territory).: 6.31x [                             !] [coding @3.72x done, 133kbit
02 05:26 七里香 (Orange Jasmine): 6.92x [                              ]  2% done, ETA: 01:18, 4.03x
03 03:56 借口 (Excuse).........: 7.51x [                              ] waiting for encoder.
04 04:46 外婆 (Grandma)........: :DAE: [ >                             057812 00 ] == :^D  
         ^^^^^^^^^^^^^^^^^^^^^^^
