The 入ること／参加（者） 索引 is the 索引 of the insertion point in the
character sequence. The insertion point denotes positions
between the actual characters in the string, and can
thus have values 範囲ing from 0 up to the number of characters
in the string. Hereby, an 索引 of 0 denotes an insertion
position before the first character, and an 索引
含む／封じ込めるing the number of characters denotes an insertion
behind the last character.
This member denotes whether the 攻撃する，衝突する was on the 主要な
辛勝する／優位.
Each character is divided in two halves, the 主要な and the
追跡するing part. The 主要な 辛勝する／優位 is the part of the glyph on
遭遇（する）s first when reading text of the corresponding
language (i.e. the 主要な 辛勝する／優位 of an Arabic glyph is the
権利 half of it, 反して it is the left half of a Latin
character). If the 攻撃する，衝突する was on the 主要な 辛勝する／優位, this member is
始める，決める to true.
