The Unicode Consortium provide a range of data files detailing the nature of code points in Unicode. These data files are machine-readable but large. Here, a set of loaders are provided to parse these files during a TeX run and set appropriate parameters in an automated fashion.
The loader parses a number of data files provided by the Unicode Consortium and when used with used Unicode-capable engine sets up a range of TeX-related parameters based on the extracted information.
From the file
UnicodeData.txt the following properties are set:
\catcode11 for all letters (Unicode class "L")
\catcode11 for all combining marks (Unicode class "M")
\sfcode999 for all code points of class "Lu" (upper case letters)
\lccodefor all of class "Ll" (lower case letters) to the code point itself, and
\uccodeto the upper case mapping (or if not given to the code point itself)
\uccodefor all of class "Lu" (upper case letters) to the code point itself, and
\lccodeto the lower case mapping (or if not given to the code point itself)
\uccodefor all of class "Lt" (title case letters) to the lower and upper case mappings (or if not given to the code point itself)
\uccodefor all other letter code points are set to the code point itself
\uccodefor non-letter code points for which an upper or lower case mapping is given
\sfcode0 (ignored) for code points of Unicode classes "Pe" (closing punctuation marks) and "Pf" (final quotation marks)
\Umathcodefor all letters (Unicode class "L") and combining marks (Unicode class "M") as TeX class 7 (var)
In the above, 'letters' refers to code points with Unicode class "L", irrespective of their TeX category code.
From the file
MathClass-15.txt the following mapping between Unicode math classes and TeX math types are set up
- "L" (large)
- "B" (binary)
- "V" (vary)
- "R" (relation)
- "O" (opening)
- "C" (closing)
- "P" (punctuation)
- "A" (alphabetic)
For each code point processed, the result is of the form
\Umathcode <codepoint> = <type> 1 <codepoint>
From the files
LineBreak.txt inter character classes for XeTeX (
\XeTeXcharclass) are set for the following classes
- "ID" (ideographic)
- "CJ" (conditional Japanese starter)
- "OP" (opener)
- "CL" (closer)
- "NS" (non-starter)
- "EX" (exclamation)
- "IS" (infix separator)
- "CM" (combining marks)
All code points of classes "ID" and "CJ" are assigned to a
\XeTeXcharclass, but for other classes this only occurs when they fall into east Asian width type "F", "H" or "W" (full-, half- and wide-width).
The following mappings between Unicode and XeTeX classes occur
- "ID" and "CJ" are class 1
- "OP" is class 2
- "CL", "NS", "EX", "IS" are class 3
- "CM" is class 256 (ignored)
as standard: these may be over-ridden by defining
\XeTeXcharclass<class> as required. (If classes "ID" or "CL" are explicitly set, the other members of the same groups above will inherit these values.)
This file does not activate XeTeX's inter-character token mechanism (
\XeTeXinterchartokenstate is not set) nor does it install any material in the inter-character token registers.
Note that this file is separate from the main loader as the data structure here may need more refinement at the macro level.
The following data files are included here with permission of the Unicode Consortium (see below):
With the exception of
MathClass.txt, which is currently not formally part of the Unicode Character Database, and
BidiMirroring-5-1-0.txt, which is a data file for Unicode 5.1.0, all of the data files here are for Unicode 13.0.0.
BidiMirroring-5-1-0.txt will never be updated and is included for OpenType font support: While
BidiMirroring.txt lists all mirror pairs in the current Unicode version, only the pairs from Unicode 5.1.0 are handled directly by the OpenType rendering system. All newer pairs have to be handled through font features.
Requests to include additional Unicode data files in this bundle are welcome. Ideally this bundle will act as a single location for all Unicode data for use by TeX systems.

unicode-data – Unicode data and loaders for TeX
This bundle provides generic access to Unicode Consortium data for TeX use. It contains a set of text files provided by the Unicode Consortium which are currently all from Unicode 8.0.0, with the exception of MathClass.txt which is not currently part of the Unicode Character Database.
Accompanying these source data are generic TeX loader files allowing this data to be used as part of TeX runs, in particular in building format files. Currently there are two loader files: one for general character set up and one for initialising XeTeX character classes as has been carried out to date by unicode-letters.tex.
The source data are distributed in accordance with the license stipulated by the Unicode Consortium. The bundle as a whole is co-ordinated by the LaTeX3 Project as a general resource for TeX users.
