[i18n] Fix sneaky unicode characters in .po files and english .jsons

[javnik36]

By-product and continuation of #1352.

This PR fixes unicode characters from Combining Diacritical Marks Unicode Block used in combination with other character that have their own glyph (e.g. found U+0301 mark preceded by char. e will be changed by character é). I only changed combination of characters where I was able to confirm that new glyph is used in given locale (and combination is rather not used).

As original EN .jsons were also touched, you may want to rebuild all .po's after this PR is merged.

List of cases that I did not make any changes:

(1st char, unicode of 2nd char, #line in file, word sequence with combination of chars, file in which combination was found)
о U+0301 29 "по́том." ru: dwl/armitages_fate.po
о U+0301 19 "во́роны" ru: tcu/union_and_disillusion.po
а U+0301 47 "замка́" ru: tfa/heart_of_the_elders_part_1.po
о U+0301 57 "Про́кляты" ru: tfa/heart_of_the_elders_part_2.po
, U+0301 130 "удно,́ слов" ru: tfa/the_city_of_archives.po
о U+0301 100 "мо́чи" ru: tfa/those_held_captive.po
о U+0301 109 "по́том." ru: tfa/those_held_captive.po
ы U+0301 1013 "временны́х" rules\ru\rules.json

Some or all of them may be correct, but I lack knowledge of Cyrillic. Tagging @Evgeny727 (hope you don't mind), you may want to check if they are correct.

Hi, in result you doesn't changed anything (at least visually), so I think it's be better to doesn't change ru files.
P.s. we adding diacritic marks manually as we nedded, so we doesn't need to change something.

Ok, I left out ru files and submitted my findings in #1355. You may take a look if you are interested :)
