From 31db2916906fccbaaf0c4906dd8f31726eb2784c Mon Sep 17 00:00:00 2001 From: Chandan Kumar Date: Thu, 29 Oct 2026 16:24:52 -0400 Subject: [PATCH] Read and write every text file and subprocess output as UTF-8 (fixes the Windows corpus failure) On Windows the default encoding is cp1252, so write_text() of the AML corpus raised UnicodeEncodeError and 'labagent launch aml' stopped at the corpus step. Name utf-8 on every text read, write and subprocess capture, and add a test that reads the source so Linux CI can catch a missing encoding. Reproduced on macOS with LC_ALL=C PYTHONUTF8=0 PYTHONCOERCECLOCALE=0: the old code fails at 'corpus', the new code completes.
