[JA]: Add a preprocessor for finding entries that use explicit kanji duplication instead of the iteration mark (々) #2217
Description
Yomitan currently fails to match dictionary entries when the scanned text uses the 々 iteration mark, but the dictionary entry uses explicit kanji duplication. For example, scanning 瑞々しい does not find an entry for 瑞瑞しい.
User scans: 瑞々しい (uses 々 iteration mark)
Dictionary contains: 瑞瑞しい
Yomitan does not find a match
