fix(ci): the invisible-character gate never matched anything - #92
Conversation
MEASURED 2026-08-27: this gate's pattern caught 0 OF 6 invisible-character test
cases. It has never detected an NBSP, zero-width space, BOM, soft hyphen, bidi
override or word joiner.
ROOT CAUSE: the pattern used UTF-8 BYTE sequences (\xc2\xa0) while grep -P
matches CHARACTERS. Bytes c2 a0 are ONE character U+00A0; \xc2\xa0 asks for TWO
characters, U+00C2 then U+00A0, which is never present.
grep -P '\xc2\xa0' -> miss
grep -P '\x{a0}' -> MATCH
Only \x00 worked, being single-byte in both readings.
FIXED: codepoint escapes; C0 control characters \x01-\x08,\x0B,\x0C,\x0E-\x1F
added (TAB/LF/CR excluded); and grep -a, without which grep skips any NUL-bearing
file as binary.
The C0 range matters: a stray BACKSPACE byte made a workflow unparseable in
developer-ecosystem, so it never ran, and this linter called it clean.
Canonical fix: hyperpolymath/empty-linter#70. 1 file(s) here.
VERIFIED: YAML re-parsed, and the corrected pattern was confirmed to catch a real
NBSP before the change was kept.

Estimated code review effort: 2 (Simple) | ~5 minutes Merge Risk: 🟡 Moderate · up to The workflow now detects the intended invisible characters, but it still allows the CI job to pass after finding them because the failure path does not return a non-zero status.

112-112: 🎯 Functional CorrectnessDo not add a separate leading-BOM check.
\x{feff}can match U+FEFF at byte offset zero when PCRE UTF mode is enabled. The current pattern instead fails to compile because it contains code points above0xFFwithout UTF mode.

Pull Request Overview
The PR successfully fixes the invisible character detection gate by migrating from byte-sequence regex to Unicode codepoint escapes and including C0 control characters. This ensures characters like NBSP and BOM are correctly identified.
While Codacy reports that the PR is up to standards, two major issues persist: the CI step currently lacks a non-zero exit code to actually fail the build when characters are detected, and it does not include Unicode bidirectional isolates (U+2066–U+2069), which are essential for preventing Trojan Source attacks. These should be addressed to ensure the gate is functionally effective and secure.
About this PR
- The PR lacks automated test scenarios or sample 'malicious' files to verify the gate's effectiveness. Consider adding a small set of test files containing the targeted characters to prevent regression of this CI logic.
Test suggestions
- Verify detection of Non-Breaking Space (U+00A0)
- Verify detection of C0 control characters like Backspace (U+0008)
- Verify detection of NUL byte (U+0000) within a source file
- Verify that files containing NUL bytes are not skipped as binary by grep
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify detection of Non-Breaking Space (U+00A0)
2. Verify detection of C0 control characters like Backspace (U+0008)
3. Verify detection of NUL byte (U+0000) within a source file
4. Verify that files containing NUL bytes are not skipped as binary by grep

🟡 MEDIUM RISK
Suggestion: Optimize grep execution and ensure the CI gate fails when characters are detected. Batching invocations using + instead of \; is more efficient, and the -r flag is redundant when using find. Additionally, the workflow identifies invisible characters but does not return a non-zero exit code; ensure the job fails if findings are greater than 0.

Measured 2026-08-27: this gate caught 0 of 6 invisible-character test cases. It has never detected an NBSP, zero-width space, BOM, soft hyphen, bidi override or word joiner.
Root cause
The pattern used UTF-8 byte sequences (
\xc2\xa0) whilegrep -Pmatches characters. Bytesc2 a0are one character U+00A0;\xc2\xa0asks for two, U+00C2 then U+00A0 — never present.Only
\x00worked, being single-byte in both readings. The gate ran, passed, and could not see what it exists to see.Fixed
\x01-\x08,\x0B,\x0C,\x0E-\x1Fadded (TAB/LF/CR excluded)grep -a— without it grep skips any NUL-bearing file as binaryThe C0 range matters: a stray backspace byte made a workflow unparseable in
developer-ecosystem, so it never ran — and this linter called it clean.Canonical fix: hyperpolymath/empty-linter#70. 1 file(s) here.
Verified: YAML re-parsed, and the corrected pattern was confirmed to catch a real NBSP before the change was kept.
