It's unreasonable to expect newbies to know that "bug 12345" means "Task T14345" except where it doesn't, so let's just standardise on the real numbers. Change-Id: I6f59febaf8fc96e80f8cfc11f4356283f461142a

/**
|
||
* Workaround for incorrect collation of Estonian language ('et') in ICU (T56168).
|
||
*
|
||
* 'W' and 'V' should not be considered the same letter for the purposes of collation in modern
|
||
* Estonian. We work around this by replacing 'W' and 'w' with 'ᴡ' U+1D21 'LATIN LETTER SMALL
|
||
* CAPITAL W' for sortkey generation, which is collated like 'W' and is not tailored to have the
|
||
* same primary weight as 'V' in Estonian.
