public static Unicode::strpos($haystack, $needle, $offset = 0) Finds the position of the first occurrence of a string in another string. Parameters string $haystack: The string to search in. string $needle: The string to find in $haystack. int $offset: If specified, start the search at this number of characters from the beginning (default 0). Return value int|false The position where $needle occurs in $haystack, always relative to the beginning (independent of $offset), or FALSE if not found.

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.

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

public static Unicode::getStatus() Gets the current status of unicode/multibyte support on this environment. Return value int The status of multibyte support.

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

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
