[tech] Integrity checks for Gemini pages

[Frank Jüdes]

Hi Stephane again,

the issue with the Unicode characters is fixed. - At least half way... - It works for diacritic characters, like the "ü" in my lastname:

                .
           .    |    .
            \   |   /
        '.   \  '  /   .'
          '. .'```'. .'
<>...:::::::`.......`:::::::..<>
<>:       Frank Jüdes        :<>
<>:..........................:<>
<><><><><><><><><><><><><><><><>

But it will not work with other Unicode characters, for example emoticons:

                .
           .    |    .
            \   |   /
        '.   \  '  /   .'
          '. .'```'. .'
<>...:::::::`.......`:::::::..<>
<>:    Frank Jüdes is a 🦆    :<>
<>:..........................:<>
<><><><><><><><><><><><><><><><>

The string-length of multibyte-characters is not calculated correctly by the /boxes/ program. Its a problem with the /boxes/ program that i cannot fix. 😟

Can you please check your string again and tell me if it works now? - Thank you very much in advance for your help.

Best regards from Charleston (WV),
     Frank/2
