标题:
🚨 PaddleOCR 无法正确识别西里尔字母（俄语）— 输出结果为音译

问题描述:
您好！感谢您开发了如此优秀的PaddleOCR工具。🇨🇳🤝🇷🇺

我在使用PaddleOCR识别俄语文本（西里尔字母）时遇到了问题。模型可以运行，但输出的不是西里尔字母，而是拉丁字母的音译结果。

问题复现

输入代码:

from paddleocr import PaddleOCR
ocr = PaddleOCR(lang="ru")  
img_path = "https://book.sibverk.ru/image/trumb/500x500/13-921550.jpg"  
result = ocr.predict(img_path)  
for line in result:  
    print(line['rec_texts'])  

实际输出:

['TMMH POCCNMCKOM 中EAEPALMN']

期望输出:

['ГИМН РОССИЙСКОЙ ФЕДЕРАЦИИ']

已尝试方案

1. 完全按照官方文档安装:

   python -m pip install paddlepaddle-gpu==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
   pip install paddleocr==3.0.0

2. 确认已设置 lang="ru" 参数
3. 测试不同图片问题依旧存在

疑问

1. 这是已知问题吗？是否有解决方案？
2. 是否需要额外下载西里尔字母的语言模型？
3. 是否存在后处理参数可以修正音译结果？

环境信息

• 操作系统: （例如 Ubuntu 22.04）
• Python版本: （例如 3.10.12）
• PaddlePaddle: 3.0.0
• PaddleOCR: 3.0.0

衷心感谢您的帮助！中国开发者的技术令人钦佩，我们俄罗斯开发者非常珍视与你们的合作！🚀

Title:
🚨 PaddleOCR Fails to Recognize Cyrillic (Russian) — Output Shows Transliteration

Description:
Hello! First, thank you for this amazing PaddleOCR tool. 🇨🇳🤝🇷🇺

I'm encountering an issue with Russian (Cyrillic) text recognition. The model runs but outputs transliterated Latin letters instead of proper Cyrillic characters.

How to Reproduce

Input Code:

from paddleocr import PaddleOCR
ocr = PaddleOCR(lang="ru")  
img_path = "https://book.sibverk.ru/image/trumb/500x500/13-921550.jpg"  
result = ocr.predict(img_path)  
for line in result:  
    print(line['rec_texts'])  

Actual Output:

['TMMH POCCNMCKOM 中EAEPALMN']

Expected Output:

['ГИМН РОССИЙСКОЙ ФЕДЕРАЦИИ']

Troubleshooting Attempted

1. Installed strictly per official docs:

   python -m pip install paddlepaddle-gpu==3.0.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
   pip install paddleocr==3.0.0

2. Verified lang="ru" parameter is set
3. Tested with multiple images — issue persists

Questions

1. Is this a known issue? Are there solutions?
2. Are additional language models required for Cyrillic?
3. Are there post-processing parameters to correct transliteration?

Environment

• OS: (e.g., Ubuntu 22.04)
• Python: (e.g., 3.10.12)
• PaddlePaddle: 3.0.0
• PaddleOCR: 3.0.0

Thank you sincerely for your help! Chinese developers' work is truly admirable, and we Russian developers deeply value this collaboration. 🚀

The same problem with the ru language. Doesn't work if you specify lang='ru'

Hi!
Many thanks for the great tool. Also joining the issue described above.
I've encountered a problem with recognizing Cyrillic characters as well. Perhaps there are some subtleties and nuances related to the ru-lang?
