Issue Response

• ✨ Introduction: Thanks for opening this issue, I am the issue bot that will help you with your questoins!
• 🎯 First round response: The answer to your question is:

如果ppocr_keys_v1.txt字典里面不包含的字，比如“纡”，想要识别的话，需要按照以下步骤进行操作：

1. 创建一个自定义字典文件，例如custom_dict.txt，并将需要识别的字符逐行添加到文件中。在这种情况下，您可以将“纡”添加到custom_dict.txt中。

2. 在配置文件中修改character_dict_path参数，将其指向您创建的自定义字典文件路径。例如，将character_dict_path设置为ppocr/utils/dict/custom_dict.txt。

3. 确保在配置文件中启用了识别空格的选项。您可以将use_space_char设置为True，以便模型能够识别空格字符。

通过以上步骤，您可以使用自定义字典来识别字典中不存在的字符，如“纡”。
