Tutorial week 4

1. There is no way to tell which encoding a text file is written in. You need a convention, such as filename extensions or standardised start. Assume that files start with a string such as "language: .....".
   • Save files in a variety of different encodings such as ISO 8859-1. ISO 8859-2, ISO 2022, BIG-5, UTF-8 etc
   • Do these look different? (In Unix, the command od -b file will show the bytes in a file)
   • Can you devise an algorithm to detect encoding from these results?
   • What would be a good string to use to test encoding?
2. Which Java fonts can support display of
   • Thai characters such as U+0E01 THAI CHARACTER KO KAI 'ก'?
   • Tamil U+0B86 TAMIL LETTER AA 'ஆ'
   • Tagalog U+1700 TAGALOG LETTER A 'ᜀ'
   • The Chinese character for dog U+72AC KANGXI RADICAL DOG '犬'
3. Write a program to determine the set of fonts that can display characters in the current locale
