Sebb commented on LANG-935:
---------------------------
If the JDK implementation was changed for the worse, then surely it may be
changed back again later?
Also, we need to ensure that the performance does not get worse for other Java
versions that are supported by the library.
> Possible performance improvement on string escape functions

> The escape functions for HTML etc. use the same code and the same
> initialisation tables for the escape and unescape functions, and while this
> is an elegant approach it leads to a number of deficiencies:
> 1. The code is very much less efficient than it could be
> 2. A new output string is created even when no conversion is required
> 3. No mapping is provided for characters that do not have a specific
> representation (for example HTML 0x101 should become ā )
> The proposal is to use a new mapping technique to address these issues
