Supported and Unsupported Characters in Data

Your data may contain characters which can have a special meaning in a different context, e.g. can be interpreted as code. Typically the symbols greater than > and less than < can cause issues because they mark the beginning/end of a HTML tag. The following table explains how such characters are treated in Pricefx.

Characters / Examples of data	Status
Special characters from range 0h – 1Fh	Will be removed, except for: t", " n", " r",
`< {any}`	Will stay unchanged
`< 5` `<5`	Will stay unchanged
`<{letter}`	Will be considered a tag and will be removed or closed (and a closing tag will be added) For example: `<b` will be `<b></b>` `<x` will be removed
`<!`	Will be removed, as this is considered a start of `<!--` which can be used for an XSS attack.
`</`	Will be considered a closing tag.
HTML	Supported HTML tags and attributes are listed here. Supported tags can be formatted/normalized, i.e. tag definition changed to lowercase, spaces removed/added, or the end of a tag changed from `<hr>` to `<hr />` etc. If a closing tag in paired tags is missing, it will be added. Paired tags which are not defined logically will be removed, e.g. `<pre></pre>` as these have no effect. (Paired tags must surround the text you want format.) Tags which are not defined logically (internally) will be removed, e.g. `<input>`, `<span>`, `<img>` – these do not make sense. In special cases, the tag `<li>` will be supplemented by a parent tag to `<ul><li></li></ul>`.
