Problem

t5memory has length restriction for segment of 2048 chars for 1 language part

In process of protection of content translate5 places some content in specific tag "t5n" with currently long property "r":

<t5:n id="1" r="09ewt1GMNtC1jNXUAFPa2poa9oq60Ym6VY66UYeXHN52eM/hlsPTDs+J1dQHAA==" n="1"/> 

This leads to exaggerated size of segment in cases where lots of small content (like integers) were protected. As result such a segment will be tossed out as problematic on import

Solution

Replace regex hash in r property with generated unique string.

<t5:n id="1" r="aB1" n="1"/> 

3 chars from combination of lower/upper case english alphabet or numbers 0..9 should be enough to cover realistic number of rules provided by customer:
62 chars to use in power of  length of 3 -> 62^3 = 238328 variations

this unique string will be saved in db as part of recognition table and will be used in place of current r content in code
