# Invariance tests
|

# Each line indicates an invariant set relationship to be tested,
|
||
# and is of the form:
|
||
#
|
||
# line := set relation set
|
||
#
|
||
# relation := '=' // has identical contents to
|
||
# := ('>' | '⊃') // is proper superset of
|
||
# := ('≥' | '⊇') // is superset of
|
||
# := ('<' | '⊂') // is proper subset of
|
||
# := ('≤' | '⊆') // is subset of
|
||
# := '!' // has no intersection
|
||
# := '?' // none of the above (they overlap, and neither contains the other)
|
||
#
|
||
# A set is a standard UnicodeSet, but where $pv can be used to express properties
|
||
#
|
||
# pv := '$' '×'? prop (('=' | ':') value)?
|
||
#
|
||
# The × indicates that the property is the previous released version.
|
||
# That is, if the version is 4.0.1, then the × version is 4.0.0
|
||
# If the value is missing, it is defaulted to true
|
||
# If the value is of the form «...», then the ... is interpreted as a regular expression
|
||
# The property can be the short or long form as in the PropertyAliases.txt
|
||
# The value (if enumerated) can be the short or long form as in PropertyValueAliases.txt
|
||
#
|
||
# A UnicodeSet is a boolean combinations of properties and character ranges, as you would see in
|
||
# Perl or other regular-expression languages. Examples:
|
||
# [$General_Category:Unassigned-[a-zA-Z]]
|
||
# For details, see http://oss.software.ibm.com/icu/userguide/unicodeSet.html
|
||
#
|
||
# WARNING: do not use \p{...} or [:...:] syntax, since those will be
|
||
# ICU's current version of properties, not the current snapshot's.
|
||
# Use the $ notation for properties (listed above) instead.
|

# When this file is parsed, an error message may contain <@>
