stri_enc_set: Set or Get Default Character Encoding in stringi¶
stri_enc_set sets the encoding used to re-encode strings internally (i.e., by R) declared to be in native encoding, see stringi-encoding and stri_enc_mark.
stri_enc_get returns the currently used default encoding.
single string; character encoding name, see stri_enc_list for the list of supported encodings.
stri_enc_get is the same as stri_enc_info(NULL)$Name.friendly.
Note that changing the default encoding may have undesired consequences. Unless you are an expert user and you know what you are doing,
stri_enc_set should only be used if ICU fails to detect your system’s encoding correctly (while testing stringi we only encountered such a situation on a very old Solaris machine). Note that ICU tries to match the encoding part of the
LC_CTYPE category as given by
If you set a default encoding that is neither a superset of ASCII, nor an 8-bit encoding, a warning will be generated, see stringi-encoding for discussion.
stri_enc_set has no effect if the system ICU assumes that the default charset is always UTF-8 (i.e., where the internal
U_CHARSET_IS_UTF8 is defined and set to 1), see stri_info.
stri_enc_set returns a string with previously used character encoding, invisibly.
stri_enc_get returns a string with current default character encoding.
