Hi, Tilman. 𩸽 is a Kanji character defined by a standard called "JIS X 0213".
about JIS X 0213 https://en.wikipedia.org/wiki/JIS_X_0213 Although this is a common character, the characters included vary from font to font and may not be included. I have given up on using fonts that do not contain these characters, but I would like to output them because they are included in Noto Sans Japanese. I read the source code for pdfbox 3.0.2. In applyGSUBRules in PDAbstractContentStream.java "char[] charArray = word.toCharArray();" In this code, I think the problem is that it is split into two char("\uD867" and "\uDE3D") , and I expect 𩸽 to be treated as a single character ("U+29E3D"). I modified the code to process each code point, and it works as expected. (All existing tests have passed.) By the way, with pdbox 2.0.31, the same code produces the expected output. **** Modified code **** private List<Integer> applyGSUBRules(GsubWorker gsubWorker, ByteArrayOutputStream out, PDType0Font font, String word) throws IOException { int[] codePointArray = word.codePoints().toArray(); List<Integer> originalGlyphIds = new ArrayList<>(word.codePointCount(0, word.length())); CmapLookup cmapLookup = font.getCmapLookup(); // convert characters into glyphIds for (int unicodeChar : codePointArray) { int glyphId = cmapLookup.getGlyphId(unicodeChar); if (glyphId <= 0) { throw new IllegalStateException( "could not find the glyphId for the character: " + unicodeChar); } originalGlyphIds.add(glyphId); } List<Integer> glyphIdsAfterGsub = gsubWorker.applyTransforms(originalGlyphIds); for (Integer glyphId : glyphIdsAfterGsub) { out.write(font.encodeGlyphId(glyphId)); } return glyphIdsAfterGsub; } 2024年5月4日(土) 20:12 Tilman Hausherr <thaush...@t-online.de>: > > Hi, > > Is it this one? 𩸽 > > According to my understanding of > https://www.compart.com/en/unicode/U+29E3D you should use \u29E3D or 𩸽 > directly.
