Unicode::GCString#
Functions#
Grapheme cluster strings#
as_array#
The grapheme clusters as one-cluster Unicode::GCStrings - what @{$gcstring} gives.
as_string#
The string, as a Perl (UTF-8) string - what "$gcstring" gives.
chars#
The number of characters (code points).
cmp#
Compare with another string by code points, as cmp does - the overloaded cmp.
columns#
The number of columns the string occupies (UAX #11).
concat#
Join with another string, re-segmenting where they meet - the overloaded . and .=.
copy#
A copy of the string.
eos#
True when the iterator position is at the end.
flag#
Get, or set, the break flag of cluster i (default: the current position).
item#
Cluster i (default: the current position) as a string.
join#
The strings given, joined with this one between them.
length#
The number of grapheme clusters.
next#
The cluster at the iterator position, advancing it; undef at the end - the overloaded <>.
pos#
The iterator position, after setting it when an argument is given (negative counts from the end).
substr#
length clusters from offset, as substr counts characters; with a replacement, those clusters are replaced in the string.
Overload glue#
as_scalarref#
A reference to the object’s name, “Unicode::GCString(0x…)”.

The line breaking class of the first grapheme base.
lbcext#
The line breaking class of the last grapheme extender, or of its base when the extender has none of its own.
lbclass#
Obsolete: the class of cluster i’s base; use lbc.
lbclass_ext#
