39.12.3 Predicates/Comparison
Use these procedures for testing whether an object is a character set,
or whether several character sets are equal or subsets of each other.
char-set-hash can be used for calculating a hash value, maybe for
usage in fast lookup procedures.
| char-set? obj
|
Scheme Procedure |
Return #t if obj is a character set, #f
otherwise.
|
| char-set= cs1 ...
|
Scheme Procedure |
Return #t if all given character sets are equal.
|
| char-set<= cs1 ...
|
Scheme Procedure |
Return #t if every character set csi is a subset
of character set csi+1.
|
| char-set-hash cs [bound]
|
Scheme Procedure |
Compute a hash value for the character set cs. If
bound is given and not #f, it restricts the
returned value to the range 0 ... bound - 1.
