daml assistant: Reading from input files fails with non-ASCII characters.

See original GitHub issue

When trying to run daml script with an input file in UTF-8 encoding that contains non-ASCII characters in a Text-typed field, it prints the following to the console and does nothing else (but doesn’t exit either):

Exception in thread "main" java.nio.charset.MalformedInputException: Input length = 1

Glad you got it working! I’ll see if we can just always default to utf-8. Reading files depending on locale is almost never useful ime.

That was it. I had selected a nonexistent locale in KDE (please don’t ask me why that is possible in the first place), so DAML fell back to the C one, which does not support UTF-8.
