perl-scalar-string 0.003 String aspects of scalars

Scalar::String is about the string part of plain Perl scalars. A scalar has a string value, which is notionally a sequence of Unicode codepoints but may be internally encoded in either ISO-8859-1 or UTF-8. In places, more so in older versions of Perl, the internal encoding shows through. To fully understand Perl strings it is necessary to understand these implementation details. This module provides functions to classify a string by encoding and to encode a string in a desired way. The module is implemented in XS, with a pure Perl backup version for systems that cannot handle XS.
