Is UTF-8 backwards compatible with ASCII?

UTF-8 is backward-compatible with ASCII and can represent any standard Unicode character. The first 128 UTF-8 characters precisely match the first 128 ASCII characters (numbered 0-127), meaning that existing ASCII text is already valid UTF-8.

Which is better ASCII or UTF-8?

All characters in ASCII can be encoded using UTF-8 without an increase in storage (both requires a byte of storage). UTF-8 has the added benefit of character support beyond “ASCII-characters”.

How do I convert a text file to ANSI?

Is ANSI and ASCII the same?

The main difference between ANSI and ASCII is the number of characters they can represent. ASCII was the first to be developed and when its limitations were reached, ANSI was one of the ways created to expand the number of characters that can be represented in an encoding.

Copy the original text.
In Notepad++, open new file, change Encoding -> pick an encoding you think the original text follows.
Paste.
Then to convert to Unicode by going again over the same menu: Encoding -> “Encode in UTF-8” (Not “Convert to UTF-8”) and hopefully it will become readable.

Is UTF-16 compatible with ASCII?

Why did UTF-8 replace the ASCII character and coding standard?

Why did UTF-8 replace the ASCII character-encoding standard? UTF-8 can store a character in more than one byte. UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte. This allowed us to represent a lot more character types, like emoji.

How to determine the encoding of a file using iconv?

you can use hexdump to look at bytes of non-7-bit-ASCII text and compare against code tables for common encodings (ISO 8859-*, UTF-8) to decide for yourself what the encoding is. iconv will use whatever input/output encoding you specify regardless of what the contents of the file are.

What is the difference between UTF-8 and US-ASCII?

7-bit ascii (aka us-ascii) is identical at a byte level to utf-8 and the 8-bit ascii extensions (iso-8859-*). So if your file only has 7-bit characters, then you can call it utf-8, iso-8859-* or us-ascii because at a byte level they are all identical.
