Title: fix parse_si for Japanese excel files

Hi.

using #parse_si 'Phonetic Properties' items for Japanese excel files,
the Phonetic items(KATAKANA) represents pronunciation hints of String(KANJI).

```

漢字(japanese KANJI)

フリガナ(this is KATAKANA for pronounciation:漢字)

```

It expected get '漢字' . but got '漢字フリガナ'.
so replace these string, because this can be caused by only ``.
