Latin Small Letter G
Sitting just past the six hexadecimal letter-digits (a–f), lowercase 'g' at ASCII code point 103 (0x67) is where Latin letters stop pulling double duty as numeric symbols and function purely as alphabetic characters. It is the seventh letter of the Latin alphabet, a consonant that alternates between a hard /ɡ/ (go, game) and soft /dʒ/ (gem, ginger) in English, and accounts for roughly 2.0 % of characters in typical corpora. Its code point sits 32 above uppercase 'G' at 71 (0x47), maintaining the single-bit case offset (bit 5) shared by all ASCII A–Z / a–z pairs.

Common Usage
Regex and substitution flag: In JavaScript, Perl, and several other regex flavors, appending the 'g' flag enables global matching — returning all occurrences rather than stopping after the first. The same mnemonic carries into sed's substitution command (s///g), where 'g' replaces all matches on a line rather than just the initial one.
Format specifier: In C-family printf-style formatting, %g selects the shorter of %e (scientific) or %f (fixed-point) representation for a floating-point value, automatically trimming trailing zeros — a convenient default for human-readable numeric output.
Typographic distinction: Lowercase 'g' is one of the few Latin letters with two widely recognized glyph forms — double-story (with a closed lower loop, common in serif and many sans-serif typefaces) and single-story (an open-tailed form frequent in handwriting and certain sans-serif designs). This distinction is a staple topic in typography education.
Diacritical variants: ğ (breve) is a distinct letter in Turkish, ġ (dot above) serves the same role in Maltese, and ģ (cedilla) appears in Latvian — each representing sounds that differ significantly from the base 'g', functioning as full letters in their respective alphabets rather than simple accented variants.
