Thank you very much for your kindness. I'll take a look.

@epsilonadmin
Thank you very much. I was relieved to know that it was strong in terms of security.
In which code part of fulltext-search.php is the character data extracted by PdfToText.class.php used? ??

@epsilonadmin
Is there a possibility of security problems using TextMill.io when uploading confidential data? ??

@enya
I'm new to PHP so I'm sorry if I made a mistake. I think I'm converting the character code between lines 282 and 315 in PdfToText.class.php. How can I make the character code such as Shift-JIS convertible here? ??
I'm sorry if it's not the content to ask here.

@epsilonadmin
Thank you very much. Let's take a look at the contents.

@enya
Another question is, in which php file is the code that recognizes the pdf text when NativePHP is applied? ??

@epsilonadmin
Thank you very much.

@enya
I'm sorry, the quality of the data I passed last time was not good, so could you try it with this data?テスト用のデータ.pdf

@epsilonadmin
This is a sample, but I will send it. Thank you.bantekansan.pdf

@epsilonadmin
Yes, I did. It worked fine with Textmill.io. However, we are worried about security, so we would like to operate with Native PHP.

I'm currently using the Pro version. The index of the uploaded PDF and Excel data is garbled. What is the cause of this? ?? Is File Extraction Rules involved?
