Allow configuring suppression-remover source encoding - #1894
Conversation
Add --source-encoding so the suppression remover can scan and rewrite Java files using a specified Python codec. Keep UTF-8 as the default and preserve source bytes and line endings while editing files. Cover option parsing and an ISO-8859-1 source file through annotation restoration and rewriting.

WalkthroughThe suppression remover now accepts a configurable source encoding, with UTF-8 as the default. It validates the CLI value and uses the selected encoding to decode source files for annotation scanning and to encode rewritten files. Tests cover CLI validation and forwarding, plus ISO-8859-1 input with CR and CRLF line endings and non-ASCII comments.

It does extend editing to projects that previously failed during decoding; an interruption during a multi-file edit could leave some changes unverified. Retained concerns

- Line 45: Update source_encoding to retain the CodecInfo returned by
codecs.lookup and reject codecs whose is_text_encoding is false by raising
argparse.ArgumentTypeError before returning the value. Preserve the existing
handling for unknown codec names.

- Line 329: Replace the `source_text.splitlines(keepends=True)` mapping in the
`core.py` flow with a shared splitter that recognizes CR, LF, and CRLF but not
U+0085; normalize those terminators for tree-sitter input or translate its
LF-only row positions so annotation positions align with `original_lines`,
`apply_removals`, and diagnostic mapping in `run`.

I'll be honest I've never experimented with tree-sitter working on non-unicode sources (locations might be tricky etc.). But from the tests it seems to be working fine so this LGTM :)
Reject non-text codecs at the command line before scanning Java files. Split source only at Java line terminators and normalize CR for tree-sitter row positions, so ISO-8859-1 control characters and CR-only files do not shift annotation or diagnostic locations. Preserve CR-only endings when rewriting multiline annotations. Add regression coverage for a non-text codec and for an ISO-8859-1 file containing U+0085 and CR-only line endings.

The suppression remover currently decodes Java files as UTF-8 while scanning and editing them. Projects with another source encoding, such as ISO-8859-1, fail with
UnicodeDecodeErrorbefore the tool can remove any suppressions.Add
--source-encoding ENCODINGto select a Python text codec for Java source files. The default remains UTF-8, and the CLI rejects unknown and non-text codecs before scanning. Pass the selected encoding through annotation discovery, line counting, and each edit pass, including passes that restore needed suppressions. Decode source before giving UTF-8 bytes to tree-sitter, then encode edited text back to the selected source encoding.Use Java line terminators (CR, LF, and CRLF) consistently for source splitting and annotation position mapping. Normalize CR line endings for tree-sitter row positions, while preserving the original line endings when writing files. This also prevents ISO-8859-1's U+0085 control character from being treated as a Java line break.
Document the option with an ISO-8859-1 example. Add CLI tests for default, valid, unknown, and non-text codecs and option forwarding. Add orchestration tests with ISO-8859-1 source containing non-ASCII characters, U+0085, CRLF and CR-only endings; they exercise both restoration and rewriting, then compare the exact output bytes.
