# PropertyAliases-3.2.0.txt
|
|
#
|
|
# This file contains aliases for properties and property values used in the UCD.
|
|
# These names can be used for XML formats of UCD data, for regular-expression
|
|
# property tests, and other programmatic textual descriptions of Unicode data.
|
|
# The names are not normative, except where they correspond to normative values
|
|
# in the UCD.
|
|
#
|
|
# The names may be translated in appropriate environments, and additional
|
|
# aliases may be useful.
|
|
#
|
|
# FORMAT
|
|
#
|
|
# Each line has three fields. Where the first field is AA, BB, or ZZ, then
|
|
# the line describes a property name.
|
|
# AA - non-enumerated properties
|
|
# BB - enumerated, non-binary properties
|
|
# ZZ - binary properties and quick-check properties
|
|
#
|
|
# (The values AA, BB, and ZZ are arbitrary -- they were simply chosen to distinguish
|
|
# the different types.)
|
|
#
|
|
# Where the first field is not one of the above, the line describes a
|
|
# property value name. The first field describes the property for which that
|
|
# property value name is used. There are two special properties:
|
|
#
|
|
# xx stands for any binary property
|
|
# qc stands for any quick-check property
|
|
#
|
|
# With loose matching of property names, case distinctions, whitespace,
|
|
# and '_' are ignored.
|
|
#
|
|
# NOTE: the property value names are NOT unique across properties, especially
|
|
# with loose matches. For example,
|
|
# AL means Arabic Letter for the Bidi_Class property, and
|
|
# AL means Alpha_Left for the Combining_Class property, and
|
|
# AL means Alphabetic for the Line_Break property.
|
|
#
|
|
# In addition, some property names may be the same as some property value names:
|
|
# cc means Combining_Class property, and
|
|
# cc means the General_Category property value Control (cc)
|
|
#
|
|
# The combination of property value and property name is, however, unique.
