Reporting of characters in input help mode is unreliable if the current input language is not english

[k-kolev1985]

Steps to reproduce:

1. Add another (preferably - non-latin) input language to Windows (in my case it is bulgarian), so you have two - english and the additional one.
2. Switch to the newly added input language.
3. Preferably, switch to a multilingual speech synthesizer (e.g. eSpeak), which can read the letters from both english and the additional input language added in step 1.
4. Enable input help mode in NVDA.
5. Press each key with a letter/character from the main part of the keyboard.
6. Observe what will NVDA report for each pressed key.

Actual behavior:

In most cases, NVDA reports the letters from the english input language. Exceptions are the keys where for the english input language/layout there are symbols/punctuation characters instead of letters - there NVDA reports the corresponding characters from the additional input language.

Expected behavior:

NVDA reports the characters (symbols/punctuation/letters) for the currently active input language (e.g. in my case - bulgarian).
