The ASCII table, when defined according to the ISO-8859-11 character encoding (also known as iso-ir-166), includes ASCII control characters and ASCII printable characters. Moreover, it also includes the extended ASCII character set unique to ISO-8859-11. This character set is particularly designed to support Latin/Thai languages.
ASCII printable characters (character code 32-127)
Codes 32-127 are common for all the different variations of the ASCII table, they are called printable characters, represent letters, digits, punctuation marks, and a few miscellaneous symbols. You will find almost every character on your keyboard. Character 127 represents the command DEL.

The extended ASCII codes (character code 128-255)
ISO/IEC 8859-11:2001, Information technology — 8-bit single-byte coded graphic character sets — Part 11: Latin/Thai alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 2001. It is informally referred to as Latin/Thai. It is nearly identical to the national Thai standard TIS-620 (1990). The sole difference is that ISO/IEC 8859-11 allocates non-breaking space to code 0xA0, while TIS-620 leaves it undefined. (In practice, this small distinction is usually ignored.)
