Is the combination `\;` an escape sequence for semicolon i.e. `;`.

Pardon me for the shortness of the question before, actually I am using this "\;" to escape the ";" on Linux terminal and as well as windows. It is being used to separate the different parameters querystring of a URL. Using only ";" works for windows but not on Linux. However using "\;" instead of ";" works for both Linux and windows. 
The URL is being passed to some command for processing the resource pointed by URL.

My query was simply, Is '\;' a standard escape character for ';' on linux and windows console/shell ?
