Please add UTF-8 encoding for source function in run.R

[zhibisora]

There is such a line in run.R.

source(file.path(appwd, 'app', 'app.R'))

And I think

source(file.path(appwd, 'app', 'app.R'), encoding="utf-8")

is greater.

Without this parameter, special characters in many program files will not be recognized, such as α，β and so on. This will have a certain negative impact on genome analysis. ( And, of course, other areas may also be affected. )
