perlretut - Perl regular expressions tutorial

DESCRIPTION
0. Start with the first letter in the string 'a', 1. Try the first alternative in the first group 'abd', 2. Match 'a' followed by 'b'. So far so good, 3. 'd' in the regexp doesn't match 'c' in the string - a dead end. So backtrack two characters and pick the second alternative in the first group 'abc', 4. Match 'a' followed by 'b' followed by 'c'. We are on a roll and have satisfied the first group. Set $1 to 'abc', 5 Move on to the second group and pick the first alternative 'df', 6 Match the 'd', 7. 'f' in the regexp doesn't match 'e' in the string, so a dead end. Backtrack one character and pick the second alternative in the second group 'd', 8.
'd' matches. The second grouping is satisfied, so set $2 to 'd', 9. We are at the end of the regexp, so we are done! We have matched 'abcd' out of the string "abcde"
0. Start with the first letter in the string 't', 1. The first quantifier '.*' starts out by matching the whole string ""the cat in the hat"", 2. 'a' in the regexp element 'at' doesn't match the end of the string. Backtrack one character, 3. 'a' in the regexp element 'at' still doesn't match the last letter of the string 't', so backtrack one more character, 4. Now we can match the 'a' and the 't', 5. Move on to the third element '.*'. Since we are at the end of the string and '.*' can match 0 times, assign it the empty string, 6. We are done!

perlunicode - Unicode support in Perl

DESCRIPTION
Safest if you "use feature 'unicode_strings'", Input and Output Layers, You must convert your non-ASCII, non-UTF-8 Perl scripts to be UTF-8, "use utf8" still needed to enable UTF-8 in scripts, UTF-16 scripts autodetected
When the string has been upgraded to UTF-8, There are additional methods for regular expression patterns
Unicode Character Properties
"\p{All}", "\p{Alnum}", "\p{Any}", "\p{ASCII}", "\p{Assigned}", "\p{Blank}", "\p{Decomposition_Type: Non_Canonical}" (Short: "\p{Dt=NonCanon}"), "\p{Graph}", "\p{HorizSpace}", "\p{In=*}", "\p{PerlSpace}", "\p{PerlWord}", "\p{Posix...}", "\p{Present_In: *}" (Short: "\p{In=*}"), "\p{Print}", "\p{SpacePerl}", "\p{Title}" and "\p{Titlecase}", "\p{Unicode}", "\p{VertSpace}", "\p{Word}", "\p{XPosix...}"
[1], [2], [3], [4], [5]
Unicode Regular Expression Support Level
[1] "\N{U+...}" and "\x{...}", [2] "\p{...}" "\P{...}". This requirement is for a minimal list of properties. Perl supports these. See R2.7 for other properties, [3] Perl has "\d" "\D" "\s" "\S" "\w" "\W" "\X" "[:prop:]" "[:^prop:]", plus all the properties specified by <https://www.unicode.org/reports/tr18/#Compatibility_Properties>. These are described above in "Other Properties", [4], Regular expression lookahead, [5] "\b" "\B" meet most, but not all, the details of this requirement, but "\b{wb}" and "\B{wb}" do, as well as the stricter R2.3, [6], [7], [8] UTF-8/UTF-EBDDIC used in Perl allows not only "U+10000" to "U+10FFFF" but also beyond "U+10FFFF", [9] Unicode has rewritten this portion of UTS#18 to say that getting canonical equivalence (see UAX#15 "Unicode Normalization Forms" <https://www.unicode.org/reports/tr15>) is basically to be done at the programmer level. Use NFD to write both your regular expressions and text to match them against (you can use Unicode::Normalize), [10] Perl has "\X" and "\b{gcb}". Unicode has retracted their "Grapheme Cluster Mode", and recently added string properties, which Perl does not yet support, [11] see UAX#29 "Unicode Text Segmentation" <https://www.unicode.org/reports/tr29>,, [12] see "Wildcards in Property Values" above, [13] Perl supports all the properties in the Unicode Character Database (UCD). It does not yet support the listed properties that come from other Unicode sources, [14] The only optional property that Perl supports is Named Sequence. None of these properties are in the UCD

perlunifaq - Perl Unicode FAQ

Q and A
If the string's characters are all code point 255 or lower, Perl outputs bytes that match those code points. This is what happens with encoded strings. It can also, though, happen with unencoded strings that happen to be all code point 255 or lower, Otherwise, Perl outputs the string encoded as UTF-8. This only happens with strings you neglected to encode. Since that should not happen, Perl also throws a "wide character" warning in this case
I lost track; what encoding is the internal format really?

perlguts - Introduction to the Perl API

DESCRIPTION
"SvIV(SV*)" ("IV") and "SvUV(SV*)" ("UV"), "SvNV(SV*)" ("double"), Strings are a bit complicated:, Byte string: "SvPVbyte(SV*, STRLEN len)" or "SvPVbyte_nolen(SV*)", UTF-8 string: "SvPVutf8(SV*, STRLEN len)" or "SvPVutf8_nolen(SV*)", You can also use "SvPV(SV*, STRLEN len)" or "SvPV_nolen(SV*)" to fetch the SV's raw internal buffer. This is tricky, though; if your Perl string is "\xff\xff", then depending on the SV's internal encoding you might get back a 2-byte OR a 4-byte "char*". Moreover, if it's the 4-byte string, that could come from either Perl "\xff\xff" stored UTF-8 encoded, or Perl "\xc3\xbf\xc3\xbf" stored as raw octets. To differentiate between these you MUST look up the SV's UTF8 bit (cf. "SvUTF8") to know whether the source Perl string is 2 characters ("SvUTF8" would be on) or 4 characters ("SvUTF8" would be off)

DESCRIPTION
Prerequisites for running Perl 5.22.1 under AmigaOS 4.1
AmigaOS 4.1 update 6 with all updates applied as of 9th October 2013, newlib.library version 53.28 or greater, AmigaOS SDK, abc-shell
Limitations of Perl under AmigaOS 4.1
Nested Piped programs can crash when run from older abc-shells, Incorrect or unexpected command line unescaping, Starting subprocesses via open has limitations, If you find any other limitations or bugs then let me know
August 2015, Port to Perl 5.22, Add handling of NIL: to afstat(), Fix inheritance of environment variables by subprocesses, Fix exec, and exit in "forked" subprocesses, Fix issue with newlib's unlink, which could cause infinite loops, Add flock() emulation using IDOS->LockRecord thanks to Tony Cook for the suggestion, Fix issue where kill was using the wrong kind of process ID, 27th November 2013, Create new installation system based on installperl links and Amiga protection bits now set correctly, Pod now defaults to text, File::Spec should now recognise an Amiga style absolute path as well as an Unix style one. Relative paths must always be Unix style, 20th November 2013, Configured to use SDK:Local/C/perl to start standard scripts, Added Amiga::Exec module with support for Wait() and AmigaOS signal numbers, 10th October 13
