in reply to Detect wrong characters

According to this random character table, ISO-8859 defines a character for every byte value. So there are no characters not defined in this charset.

Maybe you can show us a more concrete example of what you have, what you expect and the code you wrote already. Please also tell us how your code fails to produce the result you expect.

    If there are strings from a foreign language in my text, they could conflict with my encoding "ISO-8859-1". Let me give you 2 examples:

    • You have got a sentence which contains the Greek equivalent of the German term "Steuerbescheid": εκκαθαριστικό φορολογίας
    • Your text might contain a letter that looks like a small "o", but the author used the small Greek omicron "ο" which looks the same, but is technically different.

    Unfortunately, I haven't yet any code to show to you, as I don't know how to do this.

      Probably someone entered text encoded in utf8 or another foreign encoding in the fields. If you can read them, it means your editor is configured to do so. Set it to Latin 1 to spot the difference.

      You have to identify which encoding was used and hope to code a heuristic to correct those. Like the special start bytes of Utf8 wide characters.

      You will end up needing to check and trust the heuristic, or manually correct everything.

      As far as I see does ISO Latin 1 not include Greek letters. Hence you have to translate them to HTML entities.

      (I suppose that's allowed in the document's definition)
