+Uses the table found by unipropcode to look up an integer property value
+for a given codepoint. Note that many properties that are officially
+numeric are really stored as strings, and if you try to use this op
+on such a property, you'll get a meaningless position in an enum table
+instead of the value you want.
## getuniprop_str
-* `getuniprop_str(int $codepoint, int $propcode, int $pvalcode)`
+* `getuniprop_str(int $codepoint, int $propcode)`
Same thing, but fetches a string property value.
+## getuniprop_bool
+* `getuniprop_bool(int $codepoint, int $propcode)`
+Same thing, but fetches a boolean property value.
+## matchuniprop
+* `matchuniprop(int $codepoint, int $propcode, int $pvalcode)`
+Looks up a codepoint property and return 1 if it matches the pval, 0 otherwise.
+The propcode and pvalcode may be looked up with the opcodes above. (Note that
+you can use the property value name (e.g. Nd) for both lookups.)
