Special Characters in URLs

Query parameters for some Hospitality API operations require text to be entered, for example, a rate code name or a person's name. If the text includes special or multibyte characters, these characters must be URL encoded. For example, an asterisk URL encodes as %2A.

Forward slash characters (that is, /) or UTF-8 characters must be double URL-encoded so that, for example:

/ encodes as %252F

し encodes as %25E3%2581%2597

For encoding standards, refer to the RFC Series on the RFC Editor website. The standard that defines when to encode is RFC3986 (section 2.4, When to Encode or Decode).
