Braille viewer truncates ascii rendering of terminal UEB grade 2 contractions

[gerald-hartig]

Steps to reproduce:

• Start NVDA with the braille viewer active and output set to UEB grade 2
• The brl viewer shows in ascii Taskba rather than Taskbar. The braille is correct showing the grade-2 -ar contraction
• Open a notebook document and type the word Taskbar - the braille viewer is correct in brl and ascii
• Click on the Search bar on the taskbar, then on the taskbar itself
• The brl viewer again shows ascii Taskba
• At all points the braille viewer shows the correct UEB grade-2 contracted braille

Actual behavior:

• When the brl viewer is showing the title of a window ending in a grade 2 contraction, only the first ascii letter of the contraction is shown. For example, Zoom Meeting becomes Zoom Meeti as it ends with the braille contraction -ing

Expected behavior:

• The ascii rendering should show the contraction in full and not only the first letter
