When translating XML to legacy ASCII-based formats with poor
|
|
Packit |
e4b6da |
support for Unicode, such as man pages and Texinfo, there is always
|
|
Packit |
e4b6da |
the problem that Unicode characters in the source document also
|
|
Packit |
e4b6da |
have to be translated somehow.
|
|
Packit |
e4b6da |
A straightforward character set conversion from Unicode does not
|
|
Packit |
e4b6da |
suffice, because the target character set, usually US-ASCII or ISO
|
|
Packit |
e4b6da |
Latin-1, do not contain common characters such as dashes and
|
|
Packit |
e4b6da |
directional quotation marks that are widely used in XML documents.
|
|
Packit |
e4b6da |
But document formatters (man and Texinfo) allow such characters to
|
|
Packit |
e4b6da |
be entered by a markup escape: for example,
|
|
Packit |
e4b6da |
"markup">\(lq for the left directional quote
|
|
Packit |
e4b6da |
"literal">“. And if a markup-level escape is not
|
|
Packit |
e4b6da |
available, an ASCII transliteration might be used: for example,
|
|
Packit |
e4b6da |
using the ASCII less-than sign < for
|
|
Packit |
e4b6da |
the angle quotation mark ⟨.
|
|
Packit |
e4b6da |
So the Unicode character problem can be solved in two steps:
|
|
Packit |
e4b6da |
|
|
Packit |
e4b6da |
|
|
Packit |
e4b6da |
|
|
Packit |
e4b6da |
|
|
Packit |
e4b6da |
"command">utf8trans, a program included in
|
|
Packit |
e4b6da |
docbook2X, maps Unicode characters to markup-level escapes or
|
|
Packit |
e4b6da |
transliterations.
|
|
Packit |
e4b6da |
Since there is not necessarily a fixed, official mapping of
|
|
Packit |
e4b6da |
Unicode characters,
|
|
Packit |
e4b6da |
"command">utf8trans can read in user-modifiable
|
|
Packit |
e4b6da |
character mappings expressed in text files and apply them. (Unlike
|
|
Packit |
e4b6da |
most character set converters.)
|
|
Packit |
e4b6da |
In charmaps/man/roff.charmap and
|
|
Packit |
e4b6da |
charmaps/man/texi.charmap are
|
|
Packit |
e4b6da |
character maps that may be used for man-page and Texinfo
|
|
Packit |
e4b6da |
conversion. The programs
|
|
Packit |
e4b6da |
"db2x_manxml.html">
|
|
Packit |
e4b6da |
"command">db2x_manxml and
|
|
Packit |
e4b6da |
"db2x_texixml.html">
|
|
Packit |
e4b6da |
"command">db2x_texixml will apply these
|
|
Packit |
e4b6da |
character maps, or another character map specified by the user,
|
|
Packit |
e4b6da |
automatically.
|
|
Packit |
e4b6da |
|
|
Packit |
e4b6da |
|
|
Packit |
e4b6da |
The rest of the Unicode text is converted to some other
|
|
Packit |
e4b6da |
character set (encoding). For example, a French document with
|
|
Packit |
e4b6da |
accented characters (such as é)
|
|
Packit |
e4b6da |
might be converted to ISO Latin 1.
|
|
Packit |
e4b6da |
This step is applied after
|
|
Packit |
e4b6da |
"command">utf8trans character mapping, using the
|
|
Packit |
e4b6da |
|
|
Packit |

|
Packit |
e4b6da |
"command">db2x_manxml and
|
|
Packit |
e4b6da |
"db2x_texixml.html">
|
|
Packit |
