Day names abbreviations

Hello, could anybody please advice me, if (if yes, how) it is possible to abbreviate (cut) the displayed short day or month name? The automatic short strings have various length in different languages (same tag can give 2, 3 or even 4 letters). I could use expression with some fixed names, but that would make the watch face no longer automatically localized.
Temporary solved: Aligned text to left, used monospaced font and covered the rest with masking image. Still, is there any better direct solution? With expressions maybe? I do not want to make it english only.
