• String::AsciiToLower(String{Flags:AutoMap}) -> String: Changes only Latin characters. For working with other alphabets, see Unicode::ToLower

• String::AsciiToUpper(String{Flags:AutoMap}) -> String: Changes only Latin characters. For working with other alphabets, see Unicode::ToUpper

• String::SplitToList( String?, String, [ DelimeterString:Bool?, SkipEmpty:Bool?, Limit:Uint64? ]) -> List<String>

  The first argument is the source string
  The second argument is a delimiter
  The third argument includes the following parameters:

  • DelimeterString:Bool? — treating a delimiter as a string (true, by default) or a set of characters "any of" (false)
  • SkipEmpty:Bool? — whether to skip empty strings in the result, is false by default
  • Limit:Uint64? — Limits the number of fetched components (unlimited by default); if the limit is exceeded, the raw suffix of the source string is returned in the last item

• String::JoinFromList(List<String>{Flags:AutoMap}, String) -> String

• String::ToByteList(List<String>{Flags:AutoMap}) -> List<Byte>

• String::FromByteList(List<Uint8>) -> String

• String::ReplaceFirst(String{Flags:AutoMap}, String, String) -> String: Arguments: input, find, replacement

• String::ReplaceLast(String{Flags:AutoMap}, String, String) -> String: Arguments: input, find, replacement

• String::RemoveAll(String{Flags:AutoMap}, String) -> String: The second argument is interpreted as an unordered set of characters to delete

• String::RemoveFirst(String{Flags:AutoMap}, String) -> String: An unordered set of characters in the second argument, only the first encountered character from set is deleted

• String::RemoveLast(String{Flags:AutoMap}, String) -> String: An unordered set of characters in the second argument, only the last encountered character from the set is deleted
