Fix XYZ/MOL import failing on non-UTF-8 (Japanese) encoded files (4.9.1) - #133
Conversation
load_xyz_file and load_mol_file opened files with a strict utf-8 codec, so a Shift-JIS/CP932-encoded XYZ or MOL file (common on Japanese-locale Windows) raised UnicodeDecodeError and refused to load, even though only the free-form comment/title line was affected. Both now fall back through utf-8-sig, cp932, shift_jis, and euc_jp before finally decoding with errors="replace".

Chem.SDMolSupplier(file_path) reads the file itself, bypassing _read_text_lines_flexible entirely, so CP932/Shift-JIS-encoded .sdf files were still silently corrupted or failed to import even after the XYZ/MOL fix (code review finding on PR #133). Both SDF import call sites now decode the file flexibly, extract the first record's MOL block, and parse it via MolFromMolBlock, matching the .mol path.

144-144: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winFix the still-unresolved EUC-JP/CP932 decode order.
This exact issue was flagged on a prior revision of this file:
cp932can decode EUC-JP byte sequences such asb"\xa4\xa2"without raisingUnicodeDecodeError, but produces the wrong characters instead of theeuc_jpdecode ("あ"). Becausecp932is tried beforeeuc_jpin the tuple,_read_text_lines_flexiblewill silently return mojibake for EUC-JP files instead of falling through to the correct decoder. This directly undermines the PR's stated goal of supporting EUC-JP.The new tests added in this PR (Shift-JIS/CP932/BOM/replacement cases) do not exercise this EUC-JP-vs-CP932 conflict, so the regression is not caught by the added coverage.
Move
euc_jpbeforecp932in the encoding tuple, and add a regression test using a genuinely EUC-JP-only byte sequence (one that decodes differently, or raises, undercp932).🐛 Proposed fix

830-832: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtract the duplicated SDF-record loading sequence into a shared helper.
load_mol_file(lines 830-832) andload_mol_file_for_3d_viewing(lines 1035-1037) both run the identical sequence: flexible-decode the file, extract the first SDF record, fix the counts line, then parse withChem.MolFromMolBlock. Any future fix to this SDF-handling path (encoding order, record extraction, counts-line normalization) has to be applied in both places, which risks drift between the 2D and 3D loaders.Extract a shared helper, for example
_load_sdf_first_record_block(file_path), that returns the fixed MOL block, and call it from both sites.♻️ Proposed refactor
+ def _load_mol_block_for_path(self, file_path: str, is_sdf: bool) -> str: + """Read file_path flexibly and return a V2000-fixed MOL block, + extracting the first record when is_sdf is True.""" + raw = "".join(self._read_text_lines_flexible(file_path)) + if is_sdf: + raw = self._first_sdf_record(raw) + return self.fix_mol_block(raw)Then in
load_mol_file:- if file_path.lower().endswith(".mol"): - raw = "".join(self._read_text_lines_flexible(file_path)) - fixed_block = self.fix_mol_block(raw) - mol: Optional[Chem.Mol] = Chem.MolFromMolBlock( - fixed_block, sanitize=True, removeHs=False - ) - else: - raw = "".join(self._read_text_lines_flexible(file_path)) - fixed_block = self.fix_mol_block(self._first_sdf_record(raw)) - mol = Chem.MolFromMolBlock(fixed_block, sanitize=True, removeHs=False) + is_sdf = not file_path.lower().endswith(".mol") + fixed_block = self._load_mol_block_for_path(file_path, is_sdf) + mol: Optional[Chem.Mol] = Chem.MolFromMolBlock( + fixed_block, sanitize=True, removeHs=False + )Apply the equivalent change in
