Detailed Description

A transliterator that converts from hexadecimal Unicode escape sequences to the characters they represent.

For example, "U+0040" and '\u0040'. A default HexToUnicodeTransliterator recognizes the prefixes "U+", "u+", "&#92;U", and "&#92;u". Hex values may be upper- or lowercase. By calling the applyPattern() method, one or more custom prefix/suffix pairs may be specified. See applyPattern() for details.

Member Function Documentation

void HexToUnicodeTransliterator::applyPattern const UnicodeString   thePattern,
UErrorCode   status
 

Set the patterns recognized by this transliterator.

One or more patterns may be specified, separated by semicolons (';'). Each pattern contains zero or more prefix characters, one or more digit characters, and zero or more suffix characters. The digit characters indicates optional digits ('#') followed by required digits ('0'). The total number of digits cannot exceed 4, and must be at least 1 required digit. Use a backslash ('\') to escape any of the special characters. An empty pattern is allowed; it specifies a transliterator that does nothing.

Example: "U+0000;<###0>" specifies two patterns. The first has a prefix of "U+", exactly four digits, and no suffix. The second has a prefix of "<", between one and four digits, and a suffix of ">".

 pattern := spec | ( pattern ';' spec )
 spec := prefix-char* digit-spec suffix-char*
 digit-spec := '#'* '0'+
 prefix-char := [^special-char] | '\' special-char
 suffix-char := [^special-char] | '\' special-char
 special-char := ';' | '0' | '#' | '\'
