Method Details

toPrintableLatin1

static String toPrintableLatin1(String s)

Converts its parameter to another String which contains only printable Latin-1 characters but not leading, trailing, or consecutive spaces.

Parameters:

s - the String to convert.

Returns:

a printable Latin-1 String sans superfluous spaces.

initialize
