How to detect Portuguese text that contain diacritics?

[sickerin]

For example, these are the kind of text I want to detect. It's in Portuguese, but it seems to not be able to detect.

I have tried using

ocr = PaddleOCR(use_angle_cls=True, lang='pt', use_gpu=True)

the result I get is

[[('AAAACEEIOOOUU', 0.8221192955970764)]]

I can see that the special characters are available in the character dict (https://github.com/PaddlePaddle/PaddleOCR/blob/main/ppocr/utils/dict/latin_dict.txt), but wondering whether it requires a specific instructions to trigger.

PaddleOCR may have limited proficiency in recognizing Portuguese and might require retraining with a specialized Portuguese dataset.
