Unicode U+202F narrow no-break space legitimate French typography Mongolian Unicode Standard

💡 Result:

The Unicode character U+202F NARROW NO-BREAK SPACE (NNBSP) is a legitimate and widely accepted character for both Mongolian text and French typography [1][2][3]. Mongolian Unicode Standard U+202F was originally encoded in the General Punctuation block to address specific requirements of the Mongolian script [4][5]. In Mongolian, it is used before certain grammatical suffixes to provide a small, non-breaking space that also triggers special character shaping [1][6]. It is a fundamental component of the Mongolian Unicode Standard [6]. French Typography In French typography, U+202F is the standard recommendation for representing the "espace fine insécable" (non-breaking thin space) [1][7]. French typographic rules often require a thin, non-breaking space before specific punctuation marks (such as the semicolon, colon, exclamation mark, and question mark) and inside guillemets (« ») [3][8]. Because legacy 8-bit character sets lacked a specific character for this, the non-breaking space (U+00A0) was historically used as a common, albeit wider, approximation [9]. U+202F is now considered the preferred character for this purpose, as it maintains the correct visual balance and prevents the overly wide gaps sometimes caused by using standard non-breaking spaces [2][7]. Status and Usage While its primary encoding goal was to serve Mongolian, the Unicode Consortium designed U+202F as a general-purpose character [4]. It is widely recognized in modern digital typography and locale data (such as the Common Locale Data Repository, CLDR) as the appropriate choice for the French "espace fine insécable" and as a digit group separator in various locales [2][7]. Top_Results: [1][2][7][3][6]

Citations:

Exclude U+202F unless the policy explicitly rejects it.

The pattern matches U+202F, so valid French or Mongolian text in Markdown or AsciiDoc files can trigger a warning. End the range at \x{202e} and add a regression case.

In @.github/workflows/dogfood-gate.yml at line 135, The PATTERNS definition
should stop the U+202A–U+202F range at U+202E so U+202F narrow no-break spaces
are not flagged; update the pattern accordingly and add a regression case
covering valid French or Mongolian text containing U+202F in Markdown or
AsciiDoc.

⚪ LOW RISK

Suggestion: The -r flag is redundant when using find with -type f. Additionally, using -exec ... {} + is more efficient than -exec ... {} \; and ensures that execution errors (such as PCRE failures) are correctly reflected in the command's exit status. Consider also removing 2>/dev/null to improve CI observability.

Suggested change
-exec grep -aPrl "$PATTERNS" {} \; > /tmp/empty-lint-results.txt 2>/dev/null
-exec grep -aPl "$PATTERNS" {} + > /tmp/empty-lint-results.txt
