bool isDigit(dchar ch);

Determines if a character is a digit. It returns true for decimal digits only.

Params:

dchar ch

the character to be inspected

bool isLetter(int ch);

Determines if a character is a letter.

Params:

int ch

the character to be inspected

bool isLetterOrDigit(int ch);

Determines if a character is a letter or a decimal digit.

Params:

int ch

the character to be inspected

bool isLower(dchar ch);

Determines if a character is a lower case letter.

Params:

dchar ch

the character to be inspected

bool isTitle(dchar ch);

Determines if a character is a title case letter. In case of combined letters, only the first is upper and the second is lower. Some of these special characters can be found in the croatian and greek language.

bool isPrintable(dchar ch);

Detemines if a character is a printable character as specified in the Unicode Standard.

Params:

dchar ch
