Transforms a string according to one of the predefined transformation types. The effect of this transformation may vary by locale.

Arguments

ULSTransform( string, xform [, codepage] [, locale])

Parameters

string
The string to be converted (required).
xform
The name of the transformation to apply (required). Must be one of the following (not case sensitive):
lower - Transform so that all text is lowercase. Characters without lowercase forms (as defined by the locale) are left unchanged.
upper - Transform so that all text is uppercase. Characters without uppercase forms (as defined by the locale) are left unchanged.
compose - Transform so that all diacritical (e.g. accented) characters are represented using fully-composed forms (a single code element represents the combined character).
decompose - Transform so that all diacritical characters are represented using decomposed forms (separate code elements are used to represent the base character and the diacritical mark).
hiragana - Transform so that all Japanese phonetic characters use the Hiragana character set.
katakana - Transform so that all Japanese phonetic characters use the full-width Katakana character set.
kana - Transform so that all Japanese phonetic characters use the half-width Katakana character set.
codepage
The source codepage (a positive integer). This is the codepage with which <string> is encoded (i.e. under which it would display correctly). The default is the current process codepage.
locale
The name of the locale whose transformation rules are to be used. Locale names are usually of the form xx_YY where "xx" is a language and YY is a country (e.g. "en_US", "zh_TW", "it_IT", etc.) The default is to use the current locale as defined by the LANG and LC_* environment variables.

Returns

The transformed string, which is in the same codepage as the input string. If an error occurs during transformation, an empty string ("") is returned and the global ULSERR variable will be set to a non-zero value.
