Description

Tried aprint("rand") from docs README.md and got warning [Warning] 'rand' is not printable in this environment. seems more like an error cos I don't get any output other than the warning.

Steps/Code to Reproduce

from art import  *
aprint("rand")

Expected Behavior

one of the following at least

>>> aprint("butterfly") # print art
Ƹ̵̡Ӝ̵̨̄Ʒ 
>>> aprint("happy") # print art
 ۜ\(סּںסּَ` )/ۜ
>>> aprint("love_you",number=1,text="test")  # 2-part art
»-(¯`·.·´¯)->test<-(¯`·.·´¯)-« 
>>> aprint("random") # random 1-line art mode
'(っ◕‿◕)っ '
>>> aprint("rand")   # random 1-line art mode
't(-_-t) '

@Pyroseza Hi
Would you please give us more information about your environment(CMD,PowerShell and ...)?

[Pyroseza]

Hi @sepandhaghighi, I am using gitbash (mingw64)

[sepandhaghighi]

It seems git bash does not support all 1-Line arts.
We will filter Non-ASCII arts for rand mode in a future release

[Pyroseza]

Interesting... thanks for the feedback, looking forward to the future release

Hi there, I’ve just done some reading up and found that mingw does not start up in UTF-8 but it can be both configured in the settings and it can be configured in memory for the current session using an environment variable LANG='C.UTF-8'

My suggestion is to set this variable if it is not set, then output the characters, I don’t know if this will work for sure but more can be seen here: https://stackoverflow.com/a/36692549

I’ll be testing this shortly and confirm if it works or not, if not I will do a little more research on my side.

So bad news that did not work for me, looks like mingw64 (a.k.a. git bash) does not play nice when outputting unicode chars. I did confirm that it works great in powershell.

I found a solution but not the preferred solutio, it seems to be the way that python is launched without a UTF-8 encoding for IO, it launches windows' 'cp-1252'.

I found that if I set this particular environment variable PYTHONIOENCODING=utf-8 before running my script it works perfectly, if I try set it inside the script it does not work at all.

Here is my proof it works:

$ PYTHONIOENCODING=utf-8 py.exe -3 aprint.py
＼(◑д◐)＞∠(◑д◐)
$ PYTHONIOENCODING=utf-8 py.exe -3 aprint.py
(ᾢȍˬȍ)ᾢ ļ ļ ļ ļ ļ

This is where I found the solution:
https://stackoverflow.com/questions/4374455/how-to-set-sys-stdout-encoding-in-python-3

I still think there must be a way to set this programmatically from your lib... I'm sure of it, or at least something similar...

@Pyroseza
Thanks for your effort.
Changing PYTHONIOENCODING environment variable is not a stable solution, because it may effect other programs and also is not applicable in all environments.
I think the best solution is filtering Non-ASCII 1-line arts for rand mode.
