In Japanese, the symbols ゝゞヽヾ are iteration marks for kana (hiragana and katakana). They work just like 々 works for kanji, by repeating the character that precedes them, except that, while 々 is commonly used, ゝゞヽヾ are rarely used in modern Japanese.
Note: if you saw ヽ in the furigana space, that's probably an emphasis mark instead.
The differences between the five symbols are pretty simple:
- 々 is used with kanji.
- ゝ and ゞ are used with hiragana.
- ヽ and ヾ are used with katakana.
- ゞ and ヾ add a dakuten ゛ accent.
- ゝ and ヽ remove the accent.
The symbols ゝゞヽヾ are called ichi-no-ji-ten 一の字点, "character mark [that looks like] 一," but they're also known by the same names 々 has: kurikaeshi 繰り返し, odoriji 踊り字, etc.
