U+30B7 "シ" Katakana Letter Si Unicode Character

U+30B7 "シ" Katakana Letter Si is a character in the Japanese katakana syllabary, representing the syllable "shi" in modern usage, despite its historical designation as "si" in the Unicode standard. It is commonly used in writing foreign loanwords, onomatopoeia, and scientific terms, and it appears visually similar to a simplified, angled shape resembling a smile or three short strokes arranged to the left of a longer diagonal line. In Japanese text, it serves as a distinct phonetic unit, easily confused with the similar-looking katakana character "ツ" (tsu) due to their mirrored stroke directions, a common source of misreading for learners.
