Langchain CharacterTextSplitter vs RecursiveCharacterTextSplitter

CharacterTextSplitter is not utilizing the chunk_size and chunk_overlap parameters in its split_text method. Instead, it’s splitting the text based on a provided separator and merging the splits. This could potentially lead to chunks of text that do not adhere to the specified chunk_size and chunk_overlap.

On the other hand, RecursiveCharacterTextSplitter does take into account these parameters. Its split_text method recursively splits the text based on different separators until the length of the splits is less than the chunk_size. This approach seems more aligned with the intention of creating text chunks of a specific size and overlap.
