Hi Ticker, - I think there is a small change in the handling of lines in OsmMapDataSource.readDeleteTagsFile. The old code used line = line.trim(); This is missing now. Is that intended? - I also don't understand the line with your comment "// ??? I don't understand this" . Looks like an endless recursive call? - You sometimes replaced FileReader, but not in CombinedStyleFileLoader. Why not? We have a few places where we read files which use "#" for comment lines. Would it help to create a class for that? I made a few minor mods, see attachment.

There is some code in mkgmap/srt/SrtTextReader.java:sortForCodepage() that I don't understand; it would appear to get into a recursive loop on IOException.

Hi Ticker,
yes, and every missing close() is a brain teaser ;) We have a few places where files are opened and closed in a different method. This is likely to cause trouble in unit tests, esp. on Windows. Whereever possible we should use try-with-ressources instead of Utils.closeFile() and add a comment like in SeaGenerator line in zipFile = new ZipFile(precompSeaDir); // don't close here! when a file is intentionally kept open.

I'll do another patch for other text file handling, using StandardCharset where possible and fixing TokenScanner message for bad characters if not utf-8 and, if reasonable, allowing a BOM even if the file is opened as utf-8 anyway.

thanks for the patch.
Please review TypCompiler.CharsetProbe. BufferedReader br is not closed. Is that intended?
I see that we have a mix of "utf-8" and "UTF-8" in the mkgmap sources. I think it would be good to use StandardCharsets.UTF_8 where possible and unify the rest.
