IronPDF Fails with Non-ASCII Characters in File Paths
IronPDF fails to generate PDFs or write output files when the temp folder path contains non-ASCII characters such as Nordic symbols (ø, æ, å).
[2023-02-09 13:19:21] !!! Invalid (empty) temp path generated by operating system
[2023-02-09 13:19:21] Unknown exception
[2023-02-09 13:19:21] Warning! Failed to generate temp file path in temp directory, defaulting to working directoryIronPDF's internal path handling encounters encoding failures when the temp directory path includes non-ASCII characters. The character encoding is corrupted during path processing; for example, "ø" is misread as "osjøen", producing invalid temp paths and causing the exception.
Solution
Set TempFolderPath to a path that contains only standard ASCII characters (A-Z, a-z, 0-9, underscore, hyphen):
IronPdf.Installation.TempFolderPath = @"C:\IronPdfTemp";IronPdf.Installation.TempFolderPath = "C:\IronPdfTemp"IronPdf.Installation.TempFolderPath = "C:\IronPdfTemp"Set this property before the first call to ChromePdfRenderer. If the original user profile path contains non-ASCII characters (for example, C:\Users\TopcampMjøsa\AppData\...), redirect to a path such as C:\IronPdfTemp or another ASCII-safe location.
