Your question has to do with how RegionTextRenderFilter interacts with the specific TextExtractionStrategy you have selected.
LocationTextExtractionStrategy returns text chunks that render from a specific x/y location (generally the lower left hand corner of the text draw operation that resulted in the chunk). If the chunk extends past the bounds of the region, the full chunk is still going to get passed though the filter. Long and short: LocationTextExtractionStrategy does not provide sufficient granularity to filter individual glyphs. You could come up with your own TextExtractionStrategy that could do this - but I'll warn you now that it will be really hard to do - you'll have to effectively implement clipping path support into the render listening pipeline, extract partial chunks based on overlapping regions, etc... It's a tough nut to crack.
