QuantileOnQuantile 1.0.3

Bug Fixes

• Fixed Unicode escape sequences (\u03C4, \u03B8, \u03C1) in R source files that were causing LaTeX errors during PDF manual generation on CRAN
• These escapes were converted to actual Greek characters when roxygen2 generated the .Rd files, which LaTeX could not process
• Replaced with ASCII text equivalents (tau, theta, r)

QuantileOnQuantile 1.0.2

Bug Fixes

• Removed all Unicode characters from package files to fix LaTeX PDF generation
• Version 1.0.1 still had Greek characters in cran-comments.md and NEWS.md
