The 21-year-old goalkeeper has impressed since joining QPR on loan by earning regular Championship football - and he is strengthening his position with Northern Ireland on the international scene.
He saved a penalty from Khvicha Kvaratskhelia in a 1-0 win over Georgia last week and then kept another clean sheet against Hungary. His increasingly convincing body of work could yet create an opportunity for Charles to return to Man City with a bigger role in mind.

His ceiling has always been considered high at City, but this season is providing the sort of senior experience that is proving he can handle the demands of regular first-team football.
His loan has been celebrated as a major success by QPR, while his performances for Northern Ireland are adding another layer to his development. The timing could prove significant.
City have been found guilty of 114 of the 115 charges brought against them by the Premier League following its investigation into alleged financial rule breaches between 2009 and 2018.
Manchester City Verdict
The Premier League have confirmed that Manchester City have been found guilty of all charges related to breaching financial rules.
The charges relate to breaches between the 2008/09 and 2017/18 seasons, with the club found guilty of breaching the Premier League's financial rules.
An independent commission found that the club had artificially inflated their revenues and reduced costs by more than £900 million during the time period mentioned.
The ruling also states that Manchester City committed multiple breaches of its duties of co-operation and utmost good faith towards the Premier League, and that they were in 'significant breach' of both the Premier League and UEFA's spending limits.

City deny wrongdoing and are expected to appeal. No final punishment has been determined, but potential sanctions could include points deductions, financial penalties, transfer restrictions or even relegation.
A severe punishment could also lead to changes within City's squad.
There is already speculation that Gianluigi Donnarumma could become one of the high-profile exits if City's appeals fail and the club are hit particularly hard.
That could create an opportunity for Charles as his QPR displays and continued progress with Northern Ireland are putting him in the frame.
