iText Top 5 frequently asked questions

Two weeks are gone since the last top 5. What's new in this week's top 5?

1. Why doesn't my mail appear on the mailing list?
A question that is often sent to a private e-mail address, e.g. a users.sourceforge.net mail address.
The standard answer: please read The Rules.
2. Does iText have ligature implementation for Indian languages such as Hindi, Gujarati, Marathi, etc?
iText doesn’t have support for ligatures for Indic languages. Just as we have the ArabicLigaturizer, we need an IndicLigaturizer, but so far we haven’t found anyone who could write such a class for iText.
3. Why does iText tell me a PDF is corrupt even when it opens correctly in Adobe Reader?
Because the PDF is corrupt. Read the FAQ to find out what may be wrong.
4. How can I check if a specific character is supported in a font?
Use charExists()
5. Are there things that aren't allowed when updating a Reader enabled form?
Pretty much anything that isn’t allowed by Reader.

And that's it for this week.
