In charr: String Processing Reimagined for 'ALTREP' Strings

charr 0.2.0

• Requires charport 0.2.0 or later.

• Under the "altrep" backend, short results (at most 64 strings and 64 KiB of text) are now returned as charport charpacks: a single raw vector with no external pointer or finalizer, which is cheaper to create, copy and serialize. Larger results are still returned as charvecs. Values are unchanged; only the ALTREP class differs.

• str_trunc() and str_flatten(na.rm = TRUE) (without last) no longer call is.na() on plain character input under the "base" and "altrep" backends, so packed ALTREP input stays packed. Other input types keep stringr's behavior.

• Native-encoding detection now uses charport's check, which reads R's own UTF-8 locale flag, instead of an iconv probe.

• Under the "altrep" backend, str_conv() output that is pure ASCII is now marked as ASCII rather than as the target encoding, so it serializes in packed form in any locale.

charr 0.1.0

• Initial CRAN release.
