fix(cat-voices): escape special characters in arb

[dtscalac]

Description

The special character ' needs to be escaped in arb files by prepending another ' in front of it, otherwise it's interpreted as a start of escaping sequence. Since this would require a lot of attention while adding localizations lets disable escaping but allow relax-syntax which will show special characters as they are if they are not formed properly.

I.e. {name} would be considered a localization with name variable, {name would just simply display as {name.
