Could you make it Xšayāršā, for consistency with the name used by the hero?
I've also expanded https://trac.wildfiregames.com/wiki/SpecificNames#OldPersian to list the cuneiform and transliteration.
Moreover, you should do a sed in the *.pot and *.po files.

I suppose since we accidentally broke translation freeze earlier today (because of a script bug) that it can be fixed, would have been nice to suggest that in the original concern :S
As for the pot files, they are generated automatically;

would have been nice to suggest that in the original concern :S

Didn't I?

Nope you just asked to fix the last a.

While in xšāyaϑiya (king) the final a is short, in Xšayaṛšā (Xerxes) the last a is long: ā. Please correct.
Couldn't you just use the specific name string from the hero_xerxes_i.xml template?
(Also, the "AINames" in the pers.json file are an inconsistent mess. Something for the next alpha.)

This suggest changing the Hero name, not the release name.
Anyway, I don't particularly want to deal with this, so I won't.

Where is the concern for? If it is the po-files: rP24807.

While it is true different transliteration conventions exist (e.g. x, kh, ch, ḥ, or h for 𐎧; or ā, â, å, or aa for 𐎠), the Old Persian cuneiform is quite clear, the last vowel is explicitly long:
𐎧𐏁𐎹𐎠𐎼𐏁𐎠
x-š-y-a-r-š-a
Xšayaṛšā (or Xšayaạršā or Xšayāršā, depending on how you want to render the vocalic r)

[...] Xšayāršā [...]

(There is a typo in Xerxes' name, though, the s ought to be a š.)

No, I meant the first s in the transliteration, it has Xsayāršā [sic] instead of Xšayāršā.

Here you go: D3498.

That currently two spellings are used for this name: Xšayaṛšā and Xšayāršā.

If it is the po-files: rP24807.

The autobuild scripts have to run more than once before a string is prompted for translation. This is what's on transifex right now:

As you can see, this is the previous string.

There is something else at play

• We update the string
• We update the pot file
• Sometime during the day transifex pulls it. < If that's not done then old string appears.

Solved by rP24808.
