# Which characters and coding formats are supported by Mapp Intelligence Tracking?

Mapp Intelligence supports the UTF-8 standard.

- A request may not be larger than 7KB.
- Input is case-sensitive.

Parameters can have the data type text or figure.

- Text parameters support a maximum of 255 characters. If a parameter is configured to capture [multiple values](/v1/docs/what-are-multi-value-parameters-and-how-are-they-working) simultaneously, then each single value of the parameter can consist of up to 255 characters. Each of these scalar values is stored in the database as one parameter.
- Figure parameters support a range of decimal(12,2). That means ten digits with two decimal places (range: -9999999999.99 to 9999999999.99).

If you are using the **NoScript** segment of the pixel:

- all parameters in the "<noscript>" segment must be set according to UTF-8 and URL code standards. For example, the German "ü" as "%C3%BC". This will ensure the proper transmission of all special characters and applies to all websites regardless of coding (UTF-8, ISO-8859-1, etc.).

Certain characters are automatically **filtered out** during tracking:

- 0x00-0x1f
- '
- "
- <>\
- 0xA0 => space
- Several spaces become one.
- Trailing and ending spaces are removed.
