I solved the problem. Let me write down my solution so that someone else who encounters a similar issue might come across it.
If you cannot change the Russian characters defined by the system, add a space to the end of the English versions' names.
For example, when the word 'About' is in the form 'About', changing it to 'About ' will now be seen as a new value. By doing this, you're essentially modifying the original 'About' text, thus you can make your own adjustments since there is no Russian equivalent in the system.
Similarly, the words within the placeholder were also found with their Russian equivalents and couldn't be changed with InitTranslations().
Here, add a space to the end of the English value within the placeholder in the HTML page.
In the InitTranslations() part, translate the version with the added space to the desired language.
Also thanks to @Fox for giving information about the use of "tr" in this topic. http://community.bablosoft.com/post/136557
