public static Unicode::strlen($text) Counts the number of characters in a UTF-8 string. This is less than or equal to the byte count. Parameters string $text: The string to run the operation on. Return value int The length of the string. File core/lib/Drupal/Component/Utility/Unicode.php, line 283 Class Unicode Provides Unicode-related conversions and operations. Namespace Drupal\Component\Utility Code public static function strlen($text) { if (static::getStatus() == static::STATUS

public static Unicode::strcasecmp($str1, $str2) Compares UTF-8-encoded strings in a binary safe case-insensitive manner. Parameters string $str1: The first string. string $str2: The second string. Return value int Returns < 0 if $str1 is less than $str2; > 0 if $str1 is greater than $str2, and 0 if they are equal.

Indicates that full unicode support with the PHP mbstring extension is being used. File core/lib/Drupal/Component/Utility/Unicode.php, line 83 Class Unicode Provides Unicode-related conversions and operations. Namespace Drupal\Component\Utility Code const STATUS_MULTIBYTE = 1;

Indicates an error during check for PHP unicode support. File core/lib/Drupal/Component/Utility/Unicode.php, line 88 Class Unicode Provides Unicode-related conversions and operations. Namespace Drupal\Component\Utility Code const STATUS_ERROR = -1;

public static Unicode::setStatus($status) Sets the value for multibyte support status for the current environment. The following status keys are supported: \Drupal\Component\Utility\Unicode::STATUS_MULTIBYTE Full unicode support using an extension. \Drupal\Component\Utility\Unicode::STATUS_SINGLEBYTE Standard PHP (emulated) unicode support. \Drupal\Component\Utility\Unicode::STATUS_ERROR An error occurred. No unicode support. Parameters int $status: The new status of multibyte support. Fi

Matches Unicode characters that are word boundaries. Characters with the following General_category (gc) property values are used as word boundaries. While this does not fully conform to the Word Boundaries algorithm described in http://unicode.org/reports/tr29, as PCRE does not contain the Word_Break property table, this simpler algorithm has to do. Cc, Cf, Cn, Co, Cs: Other. Pc, Pd, Pe, Pf, Pi, Po, Ps: Punctuation. Sc, Sk, Sm, So: Symbols. Zl, Zp, Zs: Separators. Non-boundary characters

public static Unicode::mimeHeaderEncode($string) Encodes MIME/HTTP headers that contain incorrectly encoded characters. For example, Unicode::mimeHeaderEncode('tést.txt') returns "=?UTF-8?B?dMOpc3QudHh0?=". See http://www.rfc-editor.org/rfc/rfc2047.txt for more information. Notes: Only encode strings that contain non-ASCII characters. We progressively cut-off a chunk with self::truncateBytes(). This ensures each chunk starts and ends on a character boundary. Using \n as the chunk separator may

public static Unicode::mimeHeaderDecode($header) Decodes MIME/HTTP encoded header values. Parameters string $header: The header to decode. Return value string The mime-decoded header. File core/lib/Drupal/Component/Utility/Unicode.php, line 634 Class Unicode Provides Unicode-related conversions and operations. Namespace Drupal\Component\Utility Code public static function mimeHeaderDecode($header) { $callback = function($matches) { $data = ($matches[2] == 'B') ? base64_decode($

public static Unicode::lcfirst($text) Converts the first character of a UTF-8 string to lowercase. Parameters string $text: The string that will be converted.
