Frequently Asked Questions

What is the ASCII range?

Codes 0 through 127. 0-31 are control codes, 32 is space, 33-126 are printable characters, and 127 is delete. Beyond 127 belongs to extensions like Latin-1 or UTF-8.

How do I decode a hex byte sequence?

Read pairs of hex digits, convert each to its decimal value (0-255), and look up the character. For example, 48656C6C6F = 'Hello'.

Is ASCII Big-Endian or Little-Endian?

Single-byte ASCII is byte-order independent. Endianness matters only for multi-byte encodings like UTF-16.
