Turkish text. (Alex Dowad)
|
Implement mb_detect_encoding using fast text conversion filters
Regarding the optional 3rd `strict` argument to mb_detect_encoding,
the documentation states:
Controls the behaviour when string is not valid in any of the listed encodings.
If strict is set to false, the closest matching encoding will be returned;
if strict is set to true, false will be returned.
(Ref: https://www.php.net/manual/en/function.mb-detect-encoding.php)
Because of bugs in the implementation, mb_detect_encoding did not always
behave according to this description when `strict` was false.
For example:
<?php
echo var_export(mb_detect_encoding("\xc0\x00", "UTF-8", false));
// Before this commit, prints: false
// After this commit, prints: 'UTF-8'
Because `strict` is false in the above example, mb_detect_encoding
should return the 'closest matching encoding', which is UTF-8, since
that is the only candidate encoding. (Incidentally, this example shows
that using mb_detect_encoding with a single candidate encoding in
non-strict mode is useless.)
The new implementation fixes this bug. It also fixes another problem
with the old implementation as regards non-strict detection mode:
The old implementation would stop processing of the input string using
a particular candidate encoding as soon as it saw an error in that
encoding, even in non-strict mode. This means that it could not really
detect the 'closest matching encoding'; rather, what it would return
in non-strict mode was 'the encoding in which the first decoding error
is furthest from the beginning of the input string'.
In non-strict mode, the new implementation continues trying to process
the input string to its end even after seeing an error. This makes it
possible to determine in which candidate encoding the string has the
smallest number of errors, i.e. the 'closest matching encoding'.
Rejecting candidate encodings as soon as it saw an error gave the old
implementation a marked performance advantage in non-strict mode;
however, the new implementation still beats it in most cases. Here are
a few sample microbenchmark results:
UTF-8, ~100 codepoints, strict mode
Old: 0.080s (100,000 calls)
New: 0.026s (" " )
UTF-8, ~100 codepoints, non-strict mode
Old: 0.079s (100,000 calls)
New: 0.033s (" " )
UTF-8, ~10000 codepoints, strict mode
Old: 6.708s (60,000 calls)
New: 1.383s (" " )
UTF-8, ~10000 codepoints, non-strict mode
Old: 6.705s (60,000 calls)
New: 3.044s (" " )
Notice that the old implementation had almost identical performance
between strict and non-strict mode, while the new suffers a significant
performance penalty for non-strict detection. This is the cost of
implementing the behavior specified in the documentation.
A couple more sample results:
SJIS, ~10000 codepoints, strict mode
Old: 4.563s
New: 1.084s
SJIS, ~10000 codepoints, non-strict mode
Old: 4.569s
New: 2.863s
This is the only case I found where the new implementation loses:
UTF-16LE, ~10000 codepoints, non-strict mode
Old: 1.514s
New: 2.813s
The reason is because the test strings happened to be invalid right from
the first few bytes for all the candidate encodings except for UTF-16LE;
so the old implementation would immediately reject all those encodings
and only process the entire string in UTF-16LE.
I believe mb_detect_encoding could be made much faster if we identified
good criteria for when to reject candidate encodings before reaching
the end of the input string.

. mb_detect_encoding's "non-strict" mode now behaves as described in the
|
|
|
|
|
documentation. Previously, it would return false if the very first byte
|
|
|
|
|
of the input string was invalid in all candidate encodings. (Alex Dowad)

Implement Unicode conditional casing rules for Greek letter sigma
The capital Greek letter sigma (Σ) should be lowercased as σ except
when it appears at the end of a word; in that case, it should be
lowercased as the special form ς.
This rule is included in the Unicode data file SpecialCasing.txt.
The condition for applying the rule is called "Final_Sigma" and is
defined in Unicode technical report 21. The rule is:
• For the special casing form to apply, the capital letter sigma must
be preceded by 0 or more "case-ignorable" characters, preceded by
at least 1 "cased" character.
• Further, capital sigma must NOT be followed by 0 or more
case-ignorable characters and then at least 1 cased character.
"Case-ignorable" characters include certain punctuation marks, like
the apostrophe, as well as various accent marks. There are actually
close to 500 different case-ignorable characters, including accent marks
from Cyrillic, Hebrew, Armenian, Arabic, Syriac, Bengali, Gujarati,
Telugu, Tibetan, and many other alphabets. This category also includes
zero-width spaces, codepoints which indicate RTL/LTR text direction,
certain musical symbols, etc.
Since the rule involves scanning over "0 or more" of such
case-ignorable characters, it may be necessary to scan arbitrarily far
to the left and right of capital sigma to determine whether the special
lowercase form should be used or not. However, since we are trying to
be both memory-efficient and CPU-efficient, this implementation limits
how far to the left we will scan. Generally, we scan up to 63 characters
to the left looking for a "cased" character, but not more.
When scanning to the right, we go up to the end of the string if
necessary, even if it means scanning over thousands of characters.
Anyways, it is almost impossible to imagine that natural text will
include "words" with more than 63 successive apostrophes (for example)
followed by a capital sigma.
Closes GH-8096.

casing rules for the Greek letter sigma. For mb_convert_case, conditional

casing only applies to MB_CASE_LOWER and MB_CASE_TITLE modes, not to
|
|
|
|
|
MB_CASE_LOWER_SIMPLE and MB_CASE_TITLE_SIMPLE. (Alex Dowad)
