Template:Chset-ctrl4/doc

Note

This template replaces Template:chset-ctrl and is an enhancement of Template:chset-ctrl3, additionally displaying the code point in octal.

Usage

Used with Template:chset-tableformat to indicate a table cell for a control character or non-printing punctuation character.

• Parameter 1: hhhh, Hexadecimal Unicode value, 4 digits (e.g., 0020)
• Parameter 2: X, Control character name (e.g., SP), with link to appropriate article
• Parameter 3: dd, Decimal character code, 1–3 digits (e.g., 32)
• Parameter 4: ooo, Octal character code, 3 digits (e.g., 040)

For example, the first four ASCII control characters (Unicode U+0000 thru U+0003, decimal 0 through 3, octal 000 through 003) are coded as rows in a character set table like this:

{|
|{{chset-color-ctrl}}|{{chset-ctrl4|0000|[[Null character|NUL]]|0|000}}
|{{chset-color-ctrl}}|{{chset-ctrl4|0001|[[Start of heading|SOH]]|1|001}}
|{{chset-color-ctrl}}|{{chset-ctrl4|0002|[[Start of text|STX]]|2|002}}
|{{chset-color-ctrl}}|{{chset-ctrl4|0003|[[End of text|ETX]]|3|003}}
|}

Which yields:

NUL 0000 0 000

SOH 0001 1 001

STX 0002 2 002

ETX 0003 3 003

Another example illustrates the coding for a few of the ISO/IEC non-printing punctuation characters:

{|
|{{chset-color-misc}}|{{chset-ctrl4|0020|[[Space (character)|SP]]|32|040}}
|{{chset-color-misc}}|{{chset-ctrl4|00A0|[[Non-breaking space|NBSP]]|160|240}}
|{{chset-color-ctrl}}|{{chset-ctrl4|00AD|[[Soft hyphen|SHY]]|173|255}}
|}

Which yields:

SP 0020 32 040

NBSP 00A0 160 240

SHY 00AD 173 255

Chset family of templates

See ISO 8859-1, Windows-1252, and EBCDIC for examples of usage.

Header and footer rows

• Template:chset-table-header — Header and title row for a 16 column character set table
• Template:chset-table-footer — Footer row for a 16 column character set table

Character row header

• Template:chset-left — Left row code header

Character cell colors

• Template:chset-color-letter — Letter (alphabetic, syllabic or logographic) character cell color (Unicode category L)
• Template:chset-color-digit — Number character cell color (Unicode category N)
• Template:chset-color-graph — Symbol character cell color (Unicode category S)
• Template:chset-color-punct — Punctuation character cell color (Unicode category P)
• Template:chset-color-undef — Undefined/unassigned character cell color
• Template:chset-color-misc — Combining, whitespace or end-user defined character cell color (Unicode category M, Z, Co)
• Template:chset-color-ctrl — Control character cell color (Unicode category Cc, Cf). Currently treated the same as misc.
• Template:chset-color-esc — Lead byte in a multi-byte encoding (not a complete character).

For generating colours for cells by Unicode category, this script may be helpful.

Certain colours are in the process of being phased out:

• Template:chset-color-ext-punct — Extended punctuation character cell color. Intended to represent non-ASCII punctuation, this is not a category used by Unicode (and there are no corresponding ext-digit, ext-graph etc). Currently renders the same as punct.

In addition to these, boxed and slightly shaded variants of these exist in order to indicate some kind of additional information (depending on the article) like, for example, a derivation from a base codepage, a variance of definition of the corresponding codepage in different sources (to be explained in the article) or in different revisions of a code page:

• Template:chset-color-letter-box — Boxed letter character cell color
• Template:chset-color-digit-box — Boxed number character cell color
• Template:chset-color-graph-box — Boxed symbol character cell color
• Template:chset-color-punct-box — Boxed punctuation character cell color
• Template:chset-color-undef-box — Boxed undefined/unassigned character cell color
• Template:chset-color-misc-box — Boxed combining, whitespace or end-user defined character cell color
• Template:chset-color-ctrl-box — Boxed control character cell color
• Template:chset-color-esc-box — Boxed lead byte cell color
• Template:chset-color-ext-punct-box exists, but see the note above.

and

• Template:chset-color-letter-var — Shaded letter character cell color
• Template:chset-color-digit-var — Shaded number character cell color
• Template:chset-color-graph-var — Shaded symbol character cell color
• Template:chset-color-punct-var — Shaded punctuation character cell color
• Template:chset-color-undef-var — Shaded undefined/unassigned character cell color
• Template:chset-color-misc-var — Shaded combining, whitespace or end-user defined character cell color
• Template:chset-color-ctrl-var — Shaded control character cell color
• Template:chset-color-esc-var — Shaded lead byte cell color
• Template:chset-color-ext-punct-var exists, but see the note above

Please note that the boxed variants must not be used, if a cell, which is not to be marked, is surrounded by four cells, which need to be marked, as this would make the central cell appear marked as well. The shaded variants do not exhibit this problem.

For as long as there is no need to differentiate one or a few of the cells in a group from the other cells in the same group, refer to the normal (that is, the non-"box"- or "var"-type) templates further above.
