ASCII characters do represent a numerical codes of letters and other alphabetical signs.
Computers do not understand only numbers so they use this numerical codes to interpret letters into their own "language".
No; ASCII itself is the character set in this case.
Because certain standards such as ASCII have different values than an Asian character set. for example, if the letter (Asian letter here) is represented by 129h in an Asian character set, then when 129h is tried to be put into ASCII, it fails, because 129h is not a valid character in ASCII, and is then shown as a box.

Ascii is not a protocol - it describes a computer system's character set. Communication with a Modbus PLC requires an understanding of how to communicate and the protocol (set of rules) does describe this. Ascii is a set of values describing the Latin codepage set that can represent certain characters in data. There are no communications "rules" with Ascii, just a data representation.
If you are storing ASCII character set, 5 x 1024 x 1024 x 1024 characters can be held. If you are storing UTF-8 character set(s), 5 x 1024 x 1024 x 1024 / 8 characters can be held. English is a ASCII character set. Japanese and Nepalese can be UTF-8 character set(s).
ASCII blank typically refers to the blank or whitespace characters in the ASCII (American Standard Code for Information Interchange) character set. In ASCII, the most common blank character is the space (character code 32), which is used to create gaps between words. There are also other whitespace characters like tab (character code 9) and carriage return (character code 13), which serve different formatting purposes. These characters are essential for text formatting and readability in computing.
The ASCII Latin-1 character set is a subset of the Unicode standard. Specifically, the first 128 characters of Unicode (U+0000 to U+007F) directly correspond to the ASCII character set, making them identical. For the Latin-1 character set (ISO-8859-1), which extends ASCII to include additional characters (U+0080 to U+00FF), conversion to Unicode is straightforward, as these characters occupy the next range in Unicode. Thus, both sets can be easily converted without loss of information for characters within these ranges.
The binary code "01010111" translates to the ASCII character 'W'. In the binary system, each set of 8 bits represents a single character, and 'W' has the decimal value 87, which corresponds to this binary representation.
ASCII (American Standard Code for Information Interchange) is the most common format for text files in computers and on the Internet. In an ASCII file, each alphabetic, numeric, or special character is represented with a 7-bit binary number (a string of seven 0s or 1s). 128 possible characters are defined.
You can store any of the 127 characters in the ASCII table using just 7 bits. The letter A has character code 65 (0x41) in all ASCII code pages. The code simply maps to the character's glyph in the current code page so you're not actually storing the letter, you are only storing its code. On most systems, the smallest unit of storage is a byte which is typically 8 bits long. The 8th bit is used to determine whether the character is in the standard ASCII character set (0 to 127) or the extended ASCII character set (128 to 255). Only the standard character set is guaranteed to be the same on all systems (the glyphs may vary in style but always represent the same character). The extended character set varies depending on which code page is current. If using UNICODE wide-characters, the character code will consume 2 or 4 bytes. On Windows, it is always 2 bytes. But if using multi-byte character encoding or standard ASCII, it is always 1 byte,
