Dear Uno

I use UNO in Julia 1.12.6 with the command of

const uno = "C:\\boyogala.solvers\\unoampl\\uno_ampl.exe"

and in my script of

model = Model(()->AmplNLWriter.Optimizer(uno))

but, uno gives me the following errors:

--------------------- START OF uno --------------------

Could you provide the reasons with it? Thanks very much.

Hi @boyogala,
Can you share your instance? I'm happy to take a look.
If you enable UTF-8 in your terminal, it should get rid of the 鈹€ characters.

Thanks, i need UTF-8 in my terminal with CHCP 65001.

Great. In the next Uno release, the statistics table will be printed with ASCII characters instead for Windows users.
