The “radio” values aren’t output

What language do you use in the form?

I use Japanese.

Try doing English and see if the result appears. I have Cyrillic and also have problems with radio buttons and checkboxes.

Just to see how to solve the problem.

Thank you. The result is as follows.

English: OK. The output is correct.
Japanese: No output.

Try adding a “u” to the file send-pdf.php

../wp-content/plugins/send-pdf-for-contact-form-7/classes/send-pdf.php

if(preg_match('/\b'.$val.'\b/iu', $valueTag)){

727, 738, 758, 769 lines of code

Thank you very much.
I tested it and found another problem.

If I mix 1-byte and 2-byte characters in the values of radio buttons and checkboxes, they are not output.
Also, a combination of 2-byte characters and some 2-byte symbols will not be output.

The test code used for the ‘Contact form 7’ form is as follows:

1. Radio button 1-byte characters and 2-byte symbols: [radio radio-1_2 use_label_element default:1 "180°" "2-byte　spaces"]
2. Radio button 2-byte characters and 2-byte symbols: [radio radio-2_2 use_label_element default:1 "全角スペース　←ここ" "全角（括弧）"]

3. Checkbox 1-byte characters and 2-byte symbols: [checkbox checkbox-1_2 use_label_element "37℃" "全角括弧と数字（123）" "2-bite　space"]
4. Checkbox 2-byte characters and 2-byte symbols: [checkbox checkbox-2_2 use_label_element "全角　スペース" "全角（括弧）"]

It may be due to the lack of font glyphs.
Could you try installing IPA fonts?

Hello,
I’ve the same issue, I use Dutch in the form.
But when I look in my file, I see the u already exists in this line:

if(preg_match(‘/\b’.$val.’\b/iu’, $valueTag)){

Is there something that I’m missing?

I hope someone can help me out.
