fix(ci): the invisible-character gate never matched anything#321hyperpolymath wants to merge 1 commit into
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.
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe workflow’s invisible-character scan now uses Unicode code-point matching, detects additional control characters and word joiners, and processes binary files as text. ChangesInvisible-character gate
Estimated code review effort: 2 (Simple) | ~5 minutes Merge Risk: 🔵 Low · up to The workflow now uses Unicode code-point matching, but its text scan does not pin a UTF-8 locale; on runners using C or POSIX, the gate could still miss non-ASCII characters. This is a bounded CI correctness risk that warrants explicit owner follow-up. Poem

Pull Request Overview
The PR successfully addresses the logic errors in the invisible-character CI gate by migrating from byte-sequence patterns to Unicode codepoint escapes and enabling binary file inspection with the -a flag. The implementation aligns with the intended requirements to expand character detection. However, the PR does not include any regression test files containing the characters the gate is meant to catch, making it difficult to verify the fix programmatically. Additionally, a minor optimization is recommended for the find command to improve execution speed and error diagnostics in CI.
About this PR
- The PR lacks automated regression tests. Adding a test file containing various invisible characters (such as U+00A0, U+200B, C0 controls, and a null byte) would ensure the gate remains functional and prevent future regressions.
Test suggestions
- Scan a source file containing a Non-Breaking Space (U+00A0) and verify detection.
- Scan a source file containing a Zero-Width Space (U+200B) and verify detection.
- Scan a source file containing a Backspace control character (\x08) and verify detection.
- Scan a source file containing a Null byte (\x00) and verify detection via the -a flag.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Scan a source file containing a Non-Breaking Space (U+00A0) and verify detection.
2. Scan a source file containing a Zero-Width Space (U+200B) and verify detection.
3. Scan a source file containing a Backspace control character (\x08) and verify detection.
4. Scan a source file containing a Null byte (\x00) and verify detection via the -a flag.

⚪ LOW RISK
Suggestion: The transition to Unicode escapes and the -a flag is correct. For better performance and reliability, you should batch the file processing and remove the redundant recursion flag. Additionally, removing the stderr redirection ensures that any issues with the regex or the grep environment are visible in the CI logs rather than failing silently.

GNU grep -P PCRE2 \x{...} LC_CTYPE C POSIX UTF-8 locale matching documentation
💡 Result:
In GNU grep, when using the Perl-compatible regular expression engine (enabled via the -P or --perl-regexp option), the syntax \x{...} is supported as a standard way to specify Unicode character code points [1][2]. Key points regarding this functionality include: 1. Syntax Support: The \x{...} sequence is part of the PCRE2 library's syntax, which GNU grep uses when -P is invoked [1][2]. Within the curly braces, you provide the hexadecimal representation of the Unicode code point (e.g., \x{20AC} for the Euro sign) [1][3]. This provides an unambiguous way to specify characters, as opposed to \xHH which is limited to two hexadecimal digits [1][4]. 2. Locale and Unicode Interaction: - When using -P, PCRE2 typically handles character matching based on the UTF-8 encoding if the environment's locale is set to a UTF-8 locale (e.g., en_US.UTF-8). - Unlike basic (BRE) or extended (ERE) regular expressions in GNU grep, which rely on the system's locale settings (LC_CTYPE) to define character classes and behavior, PCRE2 in GNU grep maintains its own internal handling of Unicode [2]. - It is important to note that PCRE2 behavior can sometimes diverge from traditional POSIX grep behavior. For instance, while POSIX grep interprets patterns based on the LC_CTYPE locale setting, -P patterns are treated as PCREs, which are generally Unicode-aware by default when the input is UTF-8 [2]. 3. POSIX Considerations: The POSIX standard for grep does not define PCRE2 or the \x{...} syntax [5]. The use of -P is a non-standard extension in GNU grep [2]. For maximum portability across different systems, standard POSIX BRE/ERE expressions should be used, though these lack the advanced Unicode escape syntax provided by PCRE2 [2][5]. 4. Documentation: For detailed technical specifications, refer to the official PCRE2 documentation (specifically the pcre2pattern and pcre2syntax manual pages), as GNU grep's behavior when using -P is governed by the underlying PCRE2 library [1][4][6][2]. Note that while GNU grep supports -P, it labels it as experimental and warns that certain features may be unimplemented or behave differently than in a standalone Perl environment [2].

site:gnu.org/software/grep/manual grep -P UTF-8 locale \x{...} LC_CTYPE
💡 Result:
GNU grep uses the LC_CTYPE locale to determine the character encoding of both the pattern and input. In a UTF-8 locale, grep -P treats input as UTF-8; in the C/POSIX locale, it treats characters as single bytes. (gnu.org)
For matching a Unicode code point with PCRE syntax:
LC_ALL=en_US.UTF-8 grep -P '\x{1F600}' file\x{...} is interpreted by PCRE as a Unicode code-point escape, but it requires an appropriate UTF-8/Unicode PCRE mode and locale. GNU’s manual specifically recommends -P for matching non-ASCII characters. (gnu.org)
To make behavior deterministic, set LC_ALL rather than only LC_CTYPE:
LC_ALL=C.UTF-8 grep -P '\x{03BB}' fileCheck available locales with:
locale -aThe locale precedence is LC_ALL, then the relevant LC_* variable, then LANG. (gnu.org)

Pin the locale for Unicode matching.
The grep -aPrl command has no explicit locale. Under the C or POSIX locale, it may treat UTF-8 input as single bytes and miss the \x{...} patterns. Set LC_ALL=C.UTF-8 for this command.

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.
