 It's important to note that ASCII characters are limited to the English alphabet and basic symbols. For languages with different character sets, other encoding standards like Unicode are used.

 It's important to note that extended ASCII character sets are limited in their support for different languages and scripts. For more comprehensive character encoding and support for a wider range of languages, Unicode has become the standard. Unicode uses a variable-length encoding scheme to represent characters from all languages and includes thousands of characters beyond the scope of extended ASCII. UTF-8, a Unicode encoding scheme, has become particularly popular due to its compatibility with ASCII and efficient use of storage space.
+Extended ASCII character sets vary depending on the specific encoding scheme being used. One of the most common extended ASCII character sets is ISO 8859-1 (Latin-1), which includes characters primarily used in Western European languages.

+. **Character 134 (†)**: Dagger
+   - Used as a typographic symbol, often indicating a footnote or reference.
