…TF-8 initialize_gitignore() and the AGENTS.md/CLAUDE.md helpers used Path.read_text()/write_text() without an encoding, so they used the locale encoding. On Windows with a non-UTF-8 code page this made `reflex init` crash: the canonical AGENTS.md contains an em dash, which cp932 cannot encode, and existing UTF-8 files with CJK text could not be decoded. On cp1252 the files were silently written in the ANSI code page. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

 [Low impact] The change is limited to files created or updated during project setup. Add a fallback for existing locale-encoded files before merging. Findings

If an existing .gitignore contains café/ saved as cp1252, this UTF-8 read raises an uncaught UnicodeDecodeError and stops reflex init. Earlier Reflex versions could read and write that file using the Windows locale. The same change affects existing AGENTS.md and CLAUDE.md files.
Keep UTF-8 for writes, but add a fallback for legacy reads and a regression test.

What and why
reflex initwrites the managed AGENTS.md section and the CLAUDE.md bridge, and merges.gitignore. It does this withPath.read_text()/write_text()and no encoding, so on Windows these files use the ANSI code page.On Japanese Windows (cp932) with Python 3.11, a plain
reflex initstops here:The canonical AGENTS.md contains an em dash. If an AGENTS.md, CLAUDE.md or
.gitignorealready has CJK text, the run fails withUnicodeDecodeErrorinstead. On cp1252 the em dash can be encoded, so there is no error, but the file is saved as cp1252 instead of UTF-8.This change passes
encoding="utf-8"to those reads and writes, aspath_ops.write_fileand #6761 (reflex rename) already do. No other files are touched. Python 3.15 turns on UTF-8 mode by default, but 3.11 to 3.14 still use the locale encoding.Tests: three new unit tests in
tests/units/utils/test_utils.pyuse non-ASCII content. With cp932 they fail without the fix (UnicodeEncodeError/UnicodeDecodeError) and pass with it. Their strings can't be encoded or decoded as cp1252 either, so they would fail on the Windows CI runners without the fix. A towncrier fragment is innews/.I used Claude Code to write this change.
