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 empty-lint workflow now detects invisible characters with Unicode codepoint escapes, includes additional control and formatting characters, and scans binary files as text. ChangesInvisible-character gate
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The workflow now detects most targeted invisible characters, but a UTF-8 BOM at the beginning of a file may still be missed without a dedicated leading-BOM check. The change is mergeable with explicit owner awareness and follow-up to close this bounded detection gap. Poem

GNU grep -P PCRE2 \x{200b} character code point value in \x{} or \o{} is too large UTF mode documentation
💡 Result:
The error "character value in \x{} or \o{} is too large" in GNU grep when using PCRE2 (the -P option) occurs primarily because PCRE2 is not operating in UTF-8 mode [1]. In PCRE2, escape sequences like \x{200b} are valid only when the engine is explicitly set to recognize multi-byte characters [2][3]. By default, PCRE2 may treat the regex as a sequence of single-byte characters, making a code point value like 0x200B (which is far greater than 255) invalid [2][1]. To resolve this issue: 1. Enable UTF-8 Mode: Ensure you are using the -P option along with an indicator that triggers UTF-8 mode. In many environments, adding the u modifier (often within the regex string if supported, e.g., (?u)) or ensuring your locale is set to a UTF-8 encoding (e.g., LC_CTYPE=en_US.UTF-8) is required [4][1]. 2. Correct Syntax: Verify there are no typos in the sequence. For example, using \x{2000-} (with a trailing hyphen) inside a character class is a common mistake that can trigger parsing errors; ensure ranges are properly formed, such as [\x{2000}-\x{200A}] [1]. 3. PCRE2 Interpretation: Be aware that \x{...} is the standard syntax for specifying Unicode code points in PCRE2 [4][2]. If your environment is compiled with specific alternate options (like PCRE2_ALT_BSUX), the handling of these escapes may change, though this is rare in standard GNU grep implementations [2][5][3]. If you continue to see the error, verify that your grep version supports -P and that your system's locale settings are correctly configured for UTF-8 [4]. Testing with a simple pattern like grep -P '\x{200B}' in a UTF-8 locale is a standard way to confirm the engine is interpreting the escape sequence as a Unicode code point rather than a literal string [4].

Add a separate leading-BOM check.
The result file depends only on grep -aPrl "$PATTERNS". The \x{feff} alternative is not a raw-byte check for EF BB BF at byte 0. Add that check and merge its output with /tmp/empty-lint-results.txt.

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.
