Utility to escape special characters in ICU number formats.

Google will use the ICU format to auto-adjust numbers based on special characters that are used in the format. This function escapes these special characters so they just show up as the character specified.

The format string is a subset of the ICU pattern set. For instance, {pattern:'#,###%'} will result in output values "1,000%", "750%", and "50%" for values 10, 7.5, and 0.5.
