stri_enc_info(enc = NULL)
NULL
or ""
for default encoding,
or a single string with encoding nameName.friendly
-- Friendly encoding name:
MIME Name or JAVA Name or ICU Canonical Name
(the first of provided ones is selected, see below);
Name.ICU
-- Encoding name as identified by ICU;
Name.*
-- other standardized encoding names,
e.g. Name.UTR22
, Name.IBM
, Name.WINDOWS
,
Name.JAVA
, Name.IANA
, Name.MIME
(some of them
may be unavailable for all the encodings);
ASCII.subset
-- is ASCII a subset of the given encoding?;
Unicode.1to1
-- for 8-bit encodings only: are all characters
translated to exactly one Unicode code point and is the translation
scheme reversible?;
CharSize.8bit
-- is this an 8-bit encoding, i.e. do we have
CharSize.min == CharSize.max
and CharSize.min == 1
?;
CharSize.min
-- minimal number of bytes used
to represent an UChar (in UTF-16, this is not the same as UChar32)
CharSize.max
-- maximal number of bytes used
to represent an UChar (in UTF-16, this is not the same as UChar32,
i.e. does not reflect the maximal code point representation size)
