List of character, symbol & sign names
Below is an overview of 85 frequently used characters, punctuation symbols or signs that are included in most fonts. These include punctuation marks and other symbols used in typography. Technically these character shapes are called glyphs. Next to each glyph name the Unicode and HTML entity are listed, as well as the ASCII code and HTML entity if these are available. I also listed the Windows ALT keystroke or the Mac equivalent that can be used to insert the character in a text.
The typeface used for most examples is Arial Bold. Small lines indicate the baseline, x-height, and the ascender and descender heights.

Understanding Regular Expressions, Special Characters, and Patterns
https://www.scribd.com/document/1708074 ... Expression

_ (underscore) Matches a comma (,), left brace ({), right brace (}), left parenthesis ( ( ), right
parenthesis ( ) ), the beginning of the string, the end of the string, or a space.
Character Pattern Ranges
A range of single-character patterns can be used to match command output. To specify a range of
single-character patterns, enclose the single-character patterns in square brackets ([ ]). Only one of these
characters must exist in the string for pattern-matching to succeed. For example, [aeiou] matches any
one of the five vowels of the lowercase alphabet, while [abcdABCD] matches any one of the first four
letters of the lowercase or uppercase alphabet.
You can simplify a range of characters by entering only the endpoints of the range separated by a dash
(–), as in the following example:
[a–dA–D]
To add a dash as a single-character pattern in the search range, include another dash and precede it with
a backslash:
[a–dA–D\–]
A bracket (]) can also be included as a single-character pattern in the range:
[a–dA–D\–\]]
Invert the matching of the range by including a caret (^) at the start of the range. The following example
matches any letter except the ones listed:
[^a–dqsv]
The following example matches anything except a right square bracket (]) or the letter d:
[^\]d]



Underscore Wildcard
Use the underscore to match the beginning of a string (^), the end of a string ($), parentheses (( )) , space
( ), braces ({}), comma (,), and underscore (_). The underscore can be used to specify that a pattern exists
anywhere in the string. For example, _1300_ matches any string that has 1300 somewhere in the string
and is preceded by or followed by a space, brace, comma, or underscore. Although _1300_ matches the
regular expression {1300_, it does not match the regular expressions 21300 and 13000t.
The underscore can replace long regular expression lists. For example, instead of specifying
^1300( ) ( )1300$ {1300, ,1300, {1300} ,1300, (1300, simply specify _1300_.


Anchor Characters
Anchoring can be used to match a regular expression pattern against the beginning or end of the string.
Regular expressions can be anchored to a portion of the string using the special characters shown in
Table D-3.
For example, the regular expression ^con matches any string that starts with con, and $sole matches any
string that ends with sole.
In addition to indicating the beginning of a string, the ^ can be used to indicate the logical function “not”
when used in a bracketed range. For example, the expression [^abcd] indicates a range that matches any
single letter, as long as it is not the letters a, b, c, and d.


Pattern Alternation
Alternation can be used to specify alternative patterns to match against a string. Separate the alternative
patterns with a vertical bar (|). Only one of the alternatives can match the string. For example, the regular
expression codex|telebit matches the string codex or the string telebit, but not both codex and telebit.


Special Characters
Certain keyboard characters have special meaning when used in regular expressions. Table D-1 lists the
keyboard characters that have special meaning.
To use these special characters as single-character patterns, remove the special meaning by preceding
each character with a backslash (\). In the following examples, single-character patterns matching a
dollar sign, an underscore, and a plus sign, respectively, are shown.
