hi guys, i use ionic.zip.dll in my project,i drop this file to assets and this work great in my project.but when i build this is not work :frowning:

what can i do for this problem, thanks in advance

okay very nice my problem was solved :slight_smile:

unity show this error:

ArgumentException: Encoding name ‘IBM437’ not supported

for solve this problem i copy all I8N.dll* from Unity installation

C:\Program Files\Unity\Editor\Data\Mono\lib\mono\unity to the
Assets folder of your project. very nice :slight_smile:

Thanks for that, this was racking my brain. I can confirm that 4 years later you still need to do this, and can confirm it works on android.
