However, UTF8 is not actually smaller than UTF16 for some UTF16 codepoints. Specifically, UTF16 code points (2 bytes) 0x800+ are 3 to 4 bytes large. The assert is mostly obeyed for source code files, but is easily violated for binary files with more random values. Wikipedia clarifies why: https://en.wikipedia.org/wiki/UTF-8#UTF-16 "Text encoded in UTF-8 will be smaller than the same text encoded in UTF-16 if there are more code points below U+0080 than in the range U+0800..U+FFFF. This is true for all modern European languages. It is often true even for languages like Chinese, due to the large number of spaces, newlines, digits, and HTML markup in typical files." 2024-05-14T18:05:58+00:00 cheneym2 acheney@nvidia.com 2024-05-14T18:05:58+00:00 urn:sha1:291b4cd82cebeed39d8c06c8208fc415dfa32a48 Slang APIs are documented as taking UTF-8 encoded shader source, though it's not explicitly documented whether it is allowed to include a BOM (Byte Order Marker). This change adds support for UTF-8 BOM markers by virtue of disposing of BOM data. As a bonus, UTF-16 input which can cleanly decode to UTF-8 is now also accepted. Throwing out the BOM on input is done by leveraging existing functionality in "determineEncoding()", however a bug exists there for null-terminated single character input, where the null byte caused a heuristic to guess UTF-16, even though the null byte isn't part of the string. The bug in "determineEncoding" is fixed by only guessing when bytes >= 2 and not looking past the end of the buffer. The 'implicit-cast' test was mistakenly relying on the bug to pass, as its expected file was being read as UTF16 and cropped to zero length due to the bug. The expected output of implicit-cast is updated to pass with the bug fix in place. The decoding of UTF-16 to UTF-8 is done through an existing 'decode' method. This change fixes a bug in UTF16-LE 'decode' where it was decoded as if it were Big-Endian. Adds 3 small tests to ensure the compiler doesn't choke on source files in UTF-8 (with BOM), UTF16-LE, or UTF16-BE. Bonus: Fixes a bug in diagnostic reporting where hex values were incorrectly translated to text, leading to incorrect, possibly truncated strings.
