description:
the default value for "sort strength" should be "ascii" in chart builder.

build number:
2.6.0.v20100323-0630

steps to reproduce:
1. open the attached report design, double click to open the chart builder.
2. click "edit group and sorting" button, check the default value of "strength".

expected result:
the default value for "strength" is "ascii".

actual result:
default value is "tertiary".

error log:
n/a
it is not bug, since chart is still using com.ibm.icu.text.collator as default sorting engine(including birt 2.1, 2.2, 2.3 and so on), so if the sort strength is not set in chart model, chart just uses default sort strength(tertiary) value of collator. for the compatibility, even after integrating the sort locale/strength of data engine into chart, chart still consider using tertiary as sort strength if there is no explicit sort strength in chart model. so the ui will show tertiary for non-explicit sort strength, also user can change this value to ascii or others in ui.
